+             Design of 3-D table insertion task
+             ----------------------------------
+
+
+ Author: I. Busko
+
+
+ Revision history:
+ 12/16/96  -  First version.
+
+
+
+
+1. Specifications / requirements:
+
+This task will perform the inverse operation performed by task txtable.
+It will insert (in the tainsert task sense) one or more 2-D tables into 
+rows of a 3-D table. Alternatively, it will create a 3-D table from the
+2-D input tables. Each column in the input 2-D table is inserted as an 
+array into a single cell at the specified row in the output table. 
+Additional scalar columns, stored in the headers of the input table by 
+txtable, will also be processed.
+
+This design proposes a first, non-sophisticated version of the task. The
+emphasis is on simplicity rather than providing support for all possible
+situations. For instance, what to do if the size of a given column in one 
+of the input tables is larger than the corresponding array size in an 
+existing output table ? Throw away extra elements ? Resize output table ? 
+But what rules to follow in order to fill back the now resized arrays ? This 
+design will solve problems like these by resorting to the simplest (from the 
+code viewpoint) solution (in this case, just ignore the extra elements).
+
+If the output table does not exist, the first input table in the list
+will define both the column information for the output table, as well as
+its maximum array size. Columns in the input and output table will be
+matched by column name. If a given column in an input table does not exist 
+in a previously existing output table, it will be ignored.
+
+The task will be named "titable" following a former proposal for naming
+the 3-D table utilities.
+
+
+
+2. Language:
+
+SPP, to allow the use of the generic datatype compiling facility, and to
+reuse significant amounts of code already developed for txtable, tximage
+and tainsert.
+
+
+
+3. Task parameters:
+
+Name     Type                  What
+
+input    file list/template   list of 2D table names with optional 
+                               row/column bracket selectors.
+output   file name            3-D table name with no row/column selectors
+                               (modified in place or created from scratch).
+row      int                   row in output table where to begin insertion.
+
+
+
+4. Data structures:
+
+The main data structures are two pointer-type column descriptor arrays, in 
+the sense defined by the tcs_ routines in the selector library. One array 
+is associated with the output table, and the other array is associated 
+with the current input table. 
+
+The output table array is sized to store column information from both the 
+actual columnar data in the input tables, as well as any scalar data 
+stored in the input table headers by the txtable task. If the output table 
+already exists, it will define the array size and contents completely. 
+If it is being created by the task, the first input table in the list will 
+define the size and content of the output descriptor array. Thus if other 
+tables in the input list have additional columns (both physical or in the 
+form of header-stored scalars), these additional columns will be ignored.
+
+
+
+5. Code structure:
+
+The listing below shows only the most important subroutines; lower-level 
+functions such as decoding header keywords are not explicited.
+
+The first section deals with creating the main column descriptor array
+for the output table. If the table does not exist, column information
+must be read from the input table columns themselves AND from eventual
+scalar columns stored in the header by txtable.
+
+The second section scans the input list and performs the actual insertion
+operation. Again, a separate piece of code exists for the cases where a
+physical column exists in the input table, or an header-stored scalar
+instead. The innermost loop takes care of reading only the selected rows 
+from the input table.
+
+- Read task parameters (clget).
+- Alloc work memory (malloc, calloc).
+- Strip output name from eventual bracket selectors (rdselect).
+- Open input list (imtopen).
+- If output table already exists (access).
+   **> Procedure TIUPDATE:
+     - Open output table (tbtopn).
+     - Create array of column pointers from output table (malloc, tcs_open).
+   **> End TIUPDATE.
+- Else
+   **> Procedure TINEW:
+      - Get first table name from input list (imtgetim).

+      - Break name into bracketed selectors (rdselect).
+      - Open input table (tbtopn).
+      - Get its total (selected and unselected) number of rows (tbpsta).
+
+      - Scalars in input table are signaled by TCTOTAL keyword in input table 
+        header. Look for it (tbhfkr) and increase number of output columns by 
+        the value of TCTOTAL.
+
+      - Create array of column pointers from input column selector and TCTOTAL
+        info (malloc, tcs_open).
+      - If no columns were matched, and no TCTOTAL keyword was found, exit.
+      - Open output table (no STDOUT allowed) (tbtopn).
+      **> Procedure TISETC:
+         - Loop over input column pointer array, if it exists.
+            - Copy column information from input to output (tbcinf, tbcdef), 
+               setting the output array size to be the input number of rows.
+         - End loop.
+         - Loop over all possible keyword sets (from 1 to TCTOTAL).
+            - Look for TCD_xxx keyword (tbhfkr).

+               - Create scalar column in output table's column array (tbcdef).
+            - End if.
+         - End loop.

+      - Rewind input list (imtrew).
+   **> End TINEW:
+- End if.
+- Initialize row counter with "row" parameter value (clgeti). Set flag if row
+  parameter is negative or INDEF.
+**> Procedure TINSERT:
+   - Loop over input list (imtlen).
+      - Get table name (imtgetim).
+      - Check if it is a table (whatfile). Skip and warn user if not.
+      - Break name into bracketed selectors (rdselect).
+      - Open input table (tbtopn).
+      - Look for ORIG_ROW keyword (tbhfkr). If found, and if "row" parameter

+      - Find how many rows were requested by row selector (trsopen, trseval,
+        trsclose).
+      - Create array of column pointers from column selector. If no columns

+               - If column names match:
+                  **> Procedure TICC:
+                     - Get output array size (tcs_totsize).
+                     - Choose the minimum in between this array size and the
+                       number of rows selected from input table. If less rows 
+                       than array elements, warn user.

+                       (tcs_intinfo).
+                       If character-type, get string size too.

+                          (trsopen, trseval, tbcgt, trsclose).
+                        - Copy buffer into designated row/column (tbapt).
+                        - If output exists and array is larger than buffer:
+                           - Set remaining elements to INDEF.
+                        - End if.
+                        - Free buffer (mfree).
+                     **> End TIROWS.
+                  **> End TICC.
+               - Else (no match), look for scalar data in input header:
+                  **> Procedure TIHC:
+                     - Look for TCTOTAL keyword (tbhfkr). If found:

+             Design of 3-D table insertion task
+             ----------------------------------
+
+
+ Author: I. Busko
+
+
+ Revision history:
+ 12/16/96  -  First version.
+ 01/15/97  -  Revised after design review.
+ 01/20/97  -  Matches version 1.0 of code.
+
+ Revision content:
+ 01/20/97: (i) internal flow control of TICOPY routine; (ii) the two main 
+           data structures now store "regular" column pointers (in the 
+           tbtable sense) instead of column pointers in the tcs_ sense;
+           (iii) inclusion of a template table.
+
+
+
+1. Specifications / requirements:
+
+This task will perform the inverse operation performed by task txtable.
+It will insert (in the tainsert task sense) one or more 2-D tables into 
+rows of a 3-D table. Alternatively, it will create a 3-D table from the
+2-D input tables. Each column in the input 2-D table is inserted as an 
+array into a single cell at the specified row in the output table. 
+Additional scalar columns, stored in the headers of the input table by 
+txtable, will also be processed. Row/column selectors in the input table
+names will be supported.
+
+This design proposes a first, non-sophisticated version of the task. The
+emphasis is on simplicity rather than providing support for all possible
+situations. For instance, what to do if the size of a given column in one 
+of the input tables is larger than the corresponding array size in an 
+existing output table ? Throw away the extra elements ? Resize output table ? 
+But what rules to follow in order to fill back the now resized arrays ? This 
+design will solve problems like these by resorting to the simplest (from the 
+code viewpoint) solution (in this case, just ignore the extra elements).
+
+If the output table does not exist, the first input table in the list
+will define both the column information for the output table, as well as
+its maximum array size. Columns in the input and output table will be
+matched by column name. If a given column in an input table does not exist 
+in a previously existing output table, it will be ignored.
+
+From design review: an existing table can be used as a template when creating 
+a new 3-D output table. If no template is supplied, the first table in the
+input list becomes the template.
+
+Because the selector mechanism does not work with scalars stored in the
+input tables' headers by task txtable, these scalars, if existent, will
+be always inserted in the output table, provided column names match.
+
+An error results when:
+- an array is found in a cell in any of the input tables,
+- datatypes in input and output columns do not agree.
+
+The task will be named "titable" following a former proposal for naming
+the 3-D table utilities.
+
+
+
+2. Language:
+
+SPP, to allow the use of the generic datatype compiling facility, and to
+reuse significant amounts of code already developed for txtable, tximage
+and tainsert.

+                               row/column bracket selectors.
+output   file name             3-D table name with no row/column selectors
+                               (modified in place or created from scratch).
+template file name             3-D template table with column selectors
+row      int                   row in output table where to begin insertion.
+
+

+4. Data structures:
+
+The main data structures are two pointer-type column descriptor arrays.
+One array is associated with the output table, and the other array is 
+associated with the current input table.

+The output table array is sized to store column information from both the 
+actual columnar data in the input tables, as well as any scalar data 
+stored in the input table headers by the txtable task. If the output table 
+already exists, it will define the array size and contents completely.

+TITABLE (Jan97)                  threed                  TITABLE (Jan97)
+
+
+
+NAME
+    titable -- Inserts 2-D tables into rows of a 3-D table.
+    
+    
+USAGE
+    titable intable outtable
+    
+    
+DESCRIPTION
+    This task  performs  the  inverse  operation  of  task  txtable:  it
+    inserts  one  or more 2-D tables into rows of a 3-D table  The input
+    may be a filename template, including wildcard  characters,  or  the
+    name  of a file (preceded by an @ sign) containing table names.  The
+    output is a single 3-D table name.   If  the  output  table  exists,
+    insertion  will  be  done  in  place.  If  the output table does not
+    exist, it will be created. The input and output tables must  not  be
+    the same.
+    
+    This  task  supports  row/column selectors in the input table names.
+    These may be used to select subsets of both rows  and  columns  from
+    the  input  table.   If  no selectors are used, all columns and rows
+    will be processed, Type 'help selectors' to  see  a  description  of
+    the selector syntax.
+    
+    When  creating  a  new  output table, the information describing its
+    columns can be taken from two sources. If parameter  'template'  has
+    the  name  of  an  existing  3-D  table,  the  column  descriptions, 
+    including maximum array sizes, will be taken  from  that  table.  If
+    'template'  has  an  invalid or null ("") value, the column-defining
+    information will be take from the first table  in  the  input  list,
+    where  its number of rows will define the maximum array size allowed
+    in the table being created. Column  selectors  are  allowed  in  the
+    template table.
+    
+    NOTE:  Both  the  output  and  template  table  names must always be
+    supplied complete, including their  extension.  Otherwise  the  task
+    may get confused on the existence of an already existing table.
+    
+    Insertion  is  performed  by first verifying if column names in both
+    input and output tables match. If a match  is  found,  values  taken
+    from  that column and all selected rows from the input table will be
+    stored  as  a  1-dimensional  array  in  a  single   cell   in   the 
+    corresponding  column  in  the  output  3-D  table.  The row in this
+    table where the insertion takes place is selected by the "row"  task
+    parameter.  It  points to the row where the first table in the input
+    list will be  inserted,  subsequent  tables  in  the  list  will  be
+    inserted  into  subsequent rows. This mechanism is superseded if the
+    "row" parameter is set  to  INDEF  or  a  negative  value,  and  the
+    keyword  "ORIG_ROW"  is found in the header of the input table. This
+    keyword is created by task txtable and its value supersedes the  row
+    counter in the task.
+    If  the  maximum  array  size  in  a target column in the output 3-D
+    table is larger than the number of selected input  rows,  the  array
+    will  be  filled  up  starting from its first element, and the empty
+    elements at the end will  be  set  to  INDEF  (or  ""  if  it  is  a
+    character  string column). If the maximum array size is smaller than
+    the number of selected rows, insertion begins by the first  selected
+    row  up  to  the  maximum  allowable  size, the remaining rows being
+    ignored.
+    
+    This task correctly handles scalars stored in the input table header
+    by  task  txtable.  Since  the selector mechanism does not work with
+    these scalars, the task will always  insert  them  into  the  output
+    table, provided there is a match in column names.
+    
+    
+PARAMETERS
+
