The following functions have operating environment dependencies:
%SCAN
-
searches for a word that is specified by its position in a string. The form of the %SCAN function is
-
%SCAN ( argument , n ,< delimiters >);

On ASCII systems, the default delimiters are
blank .< ( + & ! $ * ) ; ^ - / , %
% SYSGET
-
returns the character string that is the value of the environment variable passed as the argument. Both UNIX and SAS environment variables can be translated using the %SYSGET function. A warning message is printed if the global variable does not exist. The form of the %SYSGET function is
-
%SYSGET ( environment-variable );
For example, the following code writes the value of the HOME environment variable to the SAS log:
%let var1=%sysget(HOME); %put &var1;
