RE: Yesterdays date CLP solution

[Peter Connell <peterc@xxxxxxxxxxxxx>]

Quazy,
Using RPG400 built-in as jpcarr suggests is best. But if you are compelled
to do it in CL then here's something we used prior to RPG400.
 
             PGM        PARM(&DATE)                                   
             DCL        VAR(&DATE) TYPE(*CHAR) LEN(6)                 
             DCL        VAR(&JULDAT) TYPE(*CHAR) LEN(5)               
             DCL        VAR(&DAYN) TYPE(*DEC) LEN(3)                  
             DCL        VAR(&DAYA) TYPE(*CHAR) LEN(3)                 
             DCL        VAR(&YRN) TYPE(*DEC) LEN(3)                   
             DCL        VAR(&YRA) TYPE(*CHAR) LEN(2)                  
                                                                      
             CVTDAT     DATE(&DATE) TOVAR(&JULDAT) TOFMT(*JUL) +      
                          TOSEP(*NONE)                                
                                                                      
             CHGVAR &DAYN %SST(&JULDAT 3 3)                           
             CHGVAR &DAYN (&DAYN - 1)                                 
             IF (&DAYN = 0) DO                                        
                  CHGVAR &YRN %SST(&JULDAT 1 2)                       
/* Y1.00 Set to Y2K */                                                
                IF COND(&YRN = 00) THEN(CHGVAR VAR(&YRN) VALUE(100))  
                                                                      
                  CHGVAR &YRN (&YRN - 1)                              
                  CHGVAR &YRA &YRN                                    
                  CHGVAR &DATE ('3112' *CAT &YRA)                       
                  CVTDAT     DATE(&DATE) TOVAR(&DATE) FROMFMT(*DMY) +   
                          TOFMT(*SYSVAL) TOSEP(*NONE)                   
             ENDDO                                                      
             ELSE DO                                                    
                  CHGVAR &DAYA &DAYN                                    
                  CHGVAR %SST(&JULDAT 3 3) &DAYA                        
                  CVTDAT     DATE(&JULDAT) TOVAR(&DATE) FROMFMT(*JUL) + 
                          TOFMT(*SYSVAL) TOSEP(*NONE)                   
             ENDDO                                                      
                                                                        
             ENDPGM
 
Cheers, Peter

Subject: Yesterdays date


I am looking for a free utility or program that will give me yesterdays
date.   I was wondering if someone out there has written such a thing that
they would be willing to share.  I can do this myself but it is a pain to
check for leap year and stuff, I just didn't want to re-invent the wheel if
it is already out there. 
 
 
 
Thanks
