GASK Routines

When you use GASK routines, remember the following:

All arguments are required.
Most arguments are expressed as variable names. You can use any valid SAS variable name.
If character arguments are expressed as character strings, they must be enclosed in quotation marks.
All character variable names used as arguments must be declared in a previous LENGTH statement.
GASK routines do not change the operating state.
PUT statements display a value returned by a routine in the SAS log.
OUTPUT statements write a value that is returned by a routine to a data set.
