More REXX code. The DAYS procedure, below, computes number of days since 02/28/1900 for an mm/dd/yy date. Use the remainder of that number divided by 7 to get day of week. /*********************************************************************/ /* DAYS Compute days since 02/28/00. */ /*********************************************************************/ DAYS: Procedure; arg mm'/'dd'/'yy; mm = mm - 3; if mm < 0 then do; yy = yy - 1; mm = mm + 12; end; return( trunc((5+306*mm)/10) + dd + 365*yy + trunc(yy/4) ); /JSFisher
