# Script     : sasunixskeleton
# Version    : 1.0
# Author     : Roland Rashleigh-Berry
# Date       : 30 July 2003
# Purpose    : To create a skeleton Unix shell script that runs SAS
# SubScripts : none
# Notes      : This utility generates a script to run SAS. It handles the Unix
#              side so you can concentrate on your SAS code. When the script is
#              generated you only need amend it where the word EDIT appears. You
#              should search for it. It will appear at the top where a usage
#              message it put out of the user does not supply enough parameters
#              (if no parameters are allowed then you can delete this section).
#
#              The generated script is written to the current directory. You
#              are advised to run this script from your home directory.
#
# Usage      : sasunixskeleton
#              sasunixskeleton myscript

EDIT EDIT EDIT EDIT

Put your code here. Use \$1 to resolve the first entered parameter.
Use \$2 to resolve the second entered parameter.

\$'s get treated like the &'s in front of macro variables by scripts.
It will try to resolve a Unix variable if you use one in a format.
To get round it you have to use a slash in front of the dollar like
this "\\$" .

Your final output should be written to normal print output or you
could use a data _null_ step like the following to put the contents
of a dataset out to stdout.

data _null_;
  file stdout;
  set xxxxx;
  put @1 xxxx;
run;
