The following code demonstrates how to set an environment variable in SAS's parent shell when doing batch processing in UNIX:

From the UNIX shell:

export envar=$(sas myprog.sas)
echo $envar

Here are the contents of myprog.sas:

%let macrovar=SAS process is now complete;
data _null_;
   file stdout;
   put "&macrovar";

This example sets the environment variable "envar" to the phrase "SAS process is now complete".
