Using SYSPBUFF to Display Macro Parameter Values |
Details |
SYSPBUFF resolves to the text supplied as parameter values in the invocation of a macro that is defined with the PARMBUFF option. For name-style invocations, this text includes the parentheses and commas. Using the PARMBUFF option and SYSPBUFF, you can define a macro that accepts a varying number of parameters at each invocation.
If the macro definition includes both a set of parameters and the PARMBUFF option, the macro invocation causes the parameters to receive values and the entire invocation list of values to be assigned to SYSPBUFF.
Example |
The macro PRINTZ uses the PARMBUFF option to define a varying number of parameters and SYSPBUFF to display the parameters specified at invocation.
%macro printz/parmbuff; %put Syspbuff contains: &syspbuff; %let num=1; %let dsname=%scan(&syspbuff,&num); %do %while(&dsname ne); proc print data=&dsname; run; %let num=%eval(&num+1); %let dsname=%scan(&syspbuff,&num); %end; %mend printz; %printz(purple,red,blue,teal)
Executing this program writes this line to the SAS log:
Syspbuff contains: (purple,red,blue,teal)
