Okay, I'm half-way giving up here:

All I need to do is calculate the difference between a field FINMONTH in format I6YYM and today's date in the number of months.

I've just spent 1.5 hours trying every combination of DATECVT & DATEDIF I can come up with and I can't let it work!

This has to be possible in a single define?
(I can't believe something so simple is taking me so much time...)

TABLE FILE EMPLOYEE
PRINT FIRST_NAME
COMPUTE DT_FLD/I6YYM = 201106;
COMPUTE DT_FLD_MDYY/MDYY = DT_FLD;
COMPUTE TODAY/MDYY = '&MDYY';
COMPUTE DT_DIFF/I8 = DATEDIF(DT_FLD_MDYY, TODAY, 'M');
BY LAST_NAME
END

Enjoy!

Or simpler:

TABLE FILE EMPLOYEE
PRINT FIRST_NAME 
COMPUTE DT_FLD/I6YYM = 201106;
COMPUTE MONTHS_HIRED/I3 = YM(DT_FLD,EDIT(EDIT(&YYMD,'9999999')), 'I3');
BY LAST_NAME
END

You can also use:

&DATEYY|&DATEM

instead of:

EDIT(EDIT(&YYMD,'999999$$'))

Thanks for the response all.

It seems my 'intuitive' thinking from previous years needs to be modified a bit to arrive at a more 'webfocus-oriented' thinking...
