SAS Companion for the Microsoft Windows Environment

Macro Functions

The behavior of the %SYSGET macro function is specific to Windows:

returns the character string that is the value of the Windows environment variable passed as the argument. Both Windows and SAS environment variables can be translated using the %SYSGET function. A warning message is printed if the environment variable does not exist. The %SYSGET function has the following syntax:

%SYSGET(environment-variable-name);

Here is an example of using the %SYSGET function:

%let var1=%sysget(comspec);
%put The COMSPEC environment variable 
     is &var1;

The following line is written to the SAS log:

The COMSPEC environment variable is 
C:\winnt\system\command.exe
