Hi

I have coded following steps.

COMPUTE DATE-DAY = FUNCTION INTEGER-OF-DATE (CURR-DATE).
SUBTRACT 1 FROM DATE-DAY.
COMPUTE TRADE-DATE = FUNCTION DATE-OF-INTEGER (DATE-DAY).

here i need to subtract 1 day form the current date.
When i compile this code its gives me an error saying
""FUNCTION" was not defined as a data-name".

Can you tel me the reason why is it so.

thanks
Kamal

On your listing, the heading describes which COBOL you are using and what version, release and level. What does it show?

PP 5668-958 IBM VS COBOL II Release 3.2 09/05/90

That's what I thought....Way back level and VS COBOL II has no intrinsic functions.
IIRC, there are LE functions that do what you want......

yeah..i also searched around for ZLE functions..
i want 1 for convert date into an Integer
and another 1 for converting that interger back to date
the date is in CCYYMMDD format

What manual did you use to search around the LE functions?

i got this document
'http://www-03.ibm.com/servers/eserver/zseries/zos/le/conference/pdf/ny8243.pdf'
which tells about many services.

but it doesnt contain service for converting interger back to date.

CEECBLDY i got which converts date to integer.

Thanks for the pointer, in the summary was:
Details on callable services available in the Language Environment programming Reference. (SA22-7562-03).
Using that and searching IBM, I got:
z/OS V1R4.0 Language Environment Programming Reference.
Chapter 1, Language Environment quick reference tables, has a section, Date and time callable services, which has table 5, Date and Time Callable Services which should help.
