The following
functions have operating environment dependencies:
searches for a word
that is specified by its position in a string. Here is the form of
the %SCAN function:
%SCAN(argument,n,<delimiters>);
On ASCII systems, the default delimiters are the
following:
blank . < ( + & ! $ * ) ; ^ - / , % |
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 written if the global
variable does not exist. Here is the form of the %SYSGET function:
%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;
