function

[Tap222]

%let repmword=%sysfunc(mdy(&repmonth,1,&repyear),monname9.);

what does this function mean?

[Reeza · Accepted solution]

%SYSFUNC(function(argument(s))<, format>)

The second parameter to SYSFUNC() is a format, so whatever is processed as the first argument will get formatted as MONNAME9.

SYSFUNC

MONNAME format -> Writes date values as the name of the month.

MDY() function -> Returns a SAS date value from month, day, and year values.

So first argument is creating a date and second formats it as a month.
