#
# Phil Hodge, 10-Nov-1987 Pass Memi instead of Memr to tbbeqd.
# Phil Hodge, 28-Dec-1987 Different data types combined into one file.
# Phil Hodge, 6-Mar-1989 Allow COL_DTYPE < 0 for character columns.
# Phil Hodge, 7-Mar-1989 Eliminate TB_OFFSET, TB_CURROW, TB_MODSIZE.
# Phil Hodge, 26-Jun-1989 Use tbbcpy to copy to indef record buffer, which
# was too large by the factor SZ_REAL.
# Phil Hodge, 30-Mar-1993 Include short datatype.
# Phil Hodge, 4-Nov-1993 tbxrpt: call sscan as a subroutine, not a function.
# Phil Hodge, 14-Sep-1994 Use tbeszt for length of string; in tbxrpt, use
# gargd (dblbuf) and then nint for int & short.
# Phil Hodge, 2-Jun-1997 Replace INDEFD with TBL_INDEFD.
# Phil Hodge, 4-Mar-1998 Remove call to tbxwsk, use tbxwer & tbxoff instead.
# Phil Hodge, 27-Aug-2002 In tbxrpi and tbxrps, include an explicit test
