Can we perform the below date compare in cobol ?

WS-FROM-DATE <= WS-TO-DATE

WS-FROM-DATE PIC X(10)
WS-TO-DATE PIC X(10)

Date is of the format YYYY-MM-DD.

As long as the edit-characters are the same (as you've indicated, hyphens) then the compare will yield the condition with which you've specified or are expecting.

However, if the edit characters are a mixture of hyphens and slashes (or whatever), then yes, this will yield unexpected conditions.

If you're worried, move the numeric portion of each date into 8-Byte WS fields (format=YYYYMMDD) and then issue the compare.
