# tchsize -- Change size of table(s)

# The input tables are given by an filename template list.  The output
# is either a matching list of tables or a directory.  The number of
# input tables may be either one or match the number of output tables.
# This is based on the t_imcopy procedure.
#
# NOTE:  If task is used on a FITS table, it will be skipped.
#
# Phil Hodge, 28-Aug-1987  Task created.
# Phil Hodge,  7-Sep-1988  Change parameter names for tables.
# Phil Hodge, 26-Mar-1992  Remove calls to tbtext.
# Phil Hodge,  3-Oct-1995  Modify to use tbn instead of fnt; check for FITS.
# Phil hodge, 16-Apr-1999  Call tbttyp instead of tbparse.
