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.
