Here another different approach.

? get_max_month_day(1, 2000)
? get_max_month_day({^2003-01-31})
FUNCTION get_max_month_day(ncurr_month, ncurr_year)
IF TYPE('ncurr_month')$'DT'
ncurr_year = year(ncurr_month)
ncurr_month = month(ncurr_month)
ENDIF
FOR last_day = 28 TO 31
nmax_date = IIF(EMPTY(DATE(ncurr_year, ncurr_month, last_day)), nmax_date, DATE(ncurr_year, ncurr_month, last_day)) &&Put in a date, if it's not valid it comes out empty.
ENDFOR
RETURN DAY(nmax_date) &&Returns a numeric value indicating the last day of the month.
ENDFUNC
