Several choices come to mind but all of them revolve around knowing the 
Julian day of the year.

What happens if you:
retrieve today's date, 
CVTDAT to format *LONGJUL,
do a CHGVAR into a numeric field, 
then add 14 to the numeric value? 

Then CHGVAR from the new numeric value to *LONGJUL and 
CVTDAT the *LONGJUL to *MDY for your screen layout?

Obviously you'd think to deal with a resulting number like 2000367.

        Subject:        Can date math be done in CL ?

Standard scenario ..
CL sets up prompt screen
user choices on prompt screen control choices which RPG JOBQ printer data 
ranges

I want prompt screen default date selection range to pre-compute thru 2 
weeks 
into the future

I can write then call an RPG program to translate what that is from today 
date.
Is there a standard CMD or API already available to do this?

hypothetical example

RTVSYSVAL QDATE &TODAY

CALL   QSYS/QDATEMATH 
DAYS(14)   DIRECTION(*PLUS)   START(&TODAY)   RESULT(&RESULT)
