That's a problem, because REXX does not recognize this date format (check the manual)
I would reformat the date then check it with the DATE function:
| Code: |
Valid_Date: procedure
parse arg chkdate
wdate = translate("56781234",chkdate,"12/34/5678")
signal on SYNTAX name Valid_Date_Trap
wres = Date(,wdate,'S')
signal off SYNTAX
return(1)
Valid_Date_Trap:
Return(0) |
then you can use:
| Code: |
If Valid_Date("02/29/2007") = 0 then say "date no good!"
if Valid_Date("02/29/2008") = 1 then say "all right!" |
