If you change the WS-START-DATE field to PIC 9(09) COMP, recompile and
rerun you will see the result is 53540. After passing the 32 bit
WS-START-DATE to the intrinsics the end result comes out the
same -- shows the current date correctly.
Although the intrinsics manual declares the CALENDAR date parm as a
16 bit signed value, the intrinsic really doesn't care if you make it
a 32 bit signed value. The intermediate results are different (-11996 or
53540) but the output from the ALMANAC intrinsic yields identical correct
dates...
Yes, I've never had any need to look at the intermediate results before.
I've used FLABELINFO and FFILEINFO many times to convert these dates
(create, mod, access, restore dates) into meaningful YYYYMMDD dates
without any problems.

directly at the intermediate result held in the variable "WS-START-DATE" --
as others have mentioned, the ACTUAL value this contains is -11996, which
COBOL will mangle should you attempt to display it (truncating to 1996, and
possibly dropping the sign bit in the process)
