# Script     : showfmt
# Version    : 2.0
# Author     : Roland Rashleigh-Berry
# Date       : 22-Feb-2007
# Purpose    : To display the contents of a format that would be made available
#              if a call %allocr were made (uses SAS).
# SubScripts : showfmt_win
# SubMacros  : %allocr %attrn
# Notes      : The dollar sign of a character format name must be preceded by
#              the escape character "\" otherwise the Unix command interpreter
#              will think a Unix variable is being referred to.
# Usage      : showfmt age
#              showfmt \$cat
#===============================================================================
# PARAMETERS:
#-pos- -------------------------------description-------------------------------
#  1   Format name. Character formats must have their dollar sign preceded by
#      the escape character "\".
