I'm not sure what you would miss about RPG's SUBDUR. Take a look at
SUBTRACT-DURATION. Unless I'm blind to something, anything you can do in
RPG with SUBDIR, you can do with COBOL's SUBTRACT-DURATION. As Chuck
(CRPENCE) noted in his reply, there are several date, time, and datetime
intrinsic functions available.

As he also noted, be sure to specify CVTOPT(*DATETIME *DATE *TIME
*TIMESTAMP). You may also be interested in specifying
CVTOPT(*CVTTODATE)--which can convert a field defined in DDS as PIC 9(6)
DATFMT(YMD) as a true date field (i.e., FORMAT DATE '%y%m%d').

if you have something specific you're trying to accomplish, examples would
be easier to provide. There are probably millions of things you can do
with dates and times. I haven't found any of them especially difficult.

[COBOL400-L] Date and TimeStamp Samples?

Does anyone have some samples or a reply bail tutorial on using
Dates and TimeStamps in COBOL? What is the best way to use them? In
particular, when some of these records are updated, there are date
fields in the record itself, and a LAST_CHG_TS field .

I have gotten spoiled with RPG, especially the duration SUBDUR
opcode. I am sure I have done this before in ILE COBOL, but
honestly, I have forgotten how.

Anyone willing to share examples of or a basic tutorial for ILE
COBOL using date and timestamp fields?
