# tbegt[tbirds] -- get a single element
# These routines read a single element from a table. The value is
# read by a "primitive get element" (tbegp[]) routine into a buffer
# of the same data type as the column in the table, and that value is
# assigned to the output buffer.
#
# Phil Hodge, 17-Sep-1987 Subroutine created.
# Phil Hodge, 14-Jan-1992 Add option for text table type.
# Phil Hodge, 31-Mar-1993 Include short datatype; in tbegtb, for types other
# than boolean, change test from "if (buf == YES)" to "if (buf != NO)".
# Phil Hodge, 4-Nov-1993 Include check on row number less than one;
# call sscan as a subroutine, not a function.
# Phil Hodge, 29-Jul-1994 Change calling sequence of tbeoff.
# Phil Hodge, 9-Jun-1995 Modify for FITS tables.
# Phil Hodge, 2-Jun-1997 Replace IS_INDEFD with TBL_IS_INDEFD.
# Phil Hodge, 2-Mar-1998 Map selected row number to actual row number.
# Phil Hodge, 14-Apr-1998 Use COL_FMT directly, instead of calling tbcftg.
