+# tbynew -- Y create new table
+# Allocate space for indef record buffer, write record for size information,
+# and write each column descriptor (if any) to table.
+# This version is for column-ordered SDAS tables.  The differences between
+# this and tbxnew are that this does not allocate an indef record, a
+# default number of allocated rows is assigned if none has been specified,
+# and indef values are written to all columns of all allocated rows.
+#
+# Phil Hodge,  7-Mar-1989  Eliminate TB_MODSIZE.
+# Phil Hodge, 16-Nov-1990  Use temporary variable instead of TB_FILE(tp) when
+#	opening table file so TB_FILE(tp) will still be NULL in case of error.
+# Phil Hodge, 15-Apr-1998  Change calling sequence of tbcwcd.
