Refer to the SAS documentation for your operating environment for details. [cautionend]

Details

If the value of the operating environment variable is truncated or the variable is not defined in the operating environment, SYSGET displays a warning message in the SAS log.

Examples

This example obtains the value of two environment variables in the UNIX environment:

data _null_;
   length result $200;
   input env_var $;
   result=sysget(trim(env_var));
   put env_var= result=;
   datalines;
USER
PATH
;

Executing this DATA step for user ABCDEF displays these lines:

ENV_VAR=USER RESULT=abcdef
ENV_VAR=PATH RESULT=path-for-abcdef
