Janet,
DFSORT is quite capable of calculating the date differences between 2
dates. DATEDIFF can be used to calculate the number of days between two
date fields. The result is an 8-byte value consisting of a sign and 7
digits (sddddddd). If the first date is greater than or equal to the
second date, the sign is + (plus). If the first date is less than the
second date, the sign is - (minus).
//STEP0100 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SORTIN DD *
----+----1----+----2----+----3----+----4----+----5----+----6----+----7-
1972/01/01 1972/01/03
//SORTOUT DD SYSOUT=*
//SYSIN DD *
OPTION COPY
INREC IFOUTLEN=80,
IFTHEN=(WHEN=INIT,
OVERLAY=(81:01,10,UFF,M10,LENGTH=8, $ START CCYY/MM/DD TO CCYYMMDD
90:15,10,UFF,M10,LENGTH=8)), $ END CCYY/MM/DD TO CCYYMMDD
IFTHEN=(WHEN=INIT,
OVERLAY=(30:90,8,Y4T,DATEDIFF,81,8,Y4T)) $ DATE DIFFERENCE
//*
The output from this job is
1972/01/01 1972/01/03 +0000002
Further if you have any questions please let me know
Thanks.

As these things go, I have found new uses for my little routine. It's
strong enough to find the elapsed time for larger numbers than I intended.
So much so, I thought I'd add a function to show the elapsed time since
the beginning of my started task. The time is working wonderfully but
when I cross the more than a day boundary I'd like to display the number
of days since the start of the program.
I wound up using the
STCK-STCK difference in times since the start of the started task
+ 1972/01/01 add in base STCK time to get a STCK value again
STCKCONV convert that to DATE=YYYYMMDD TIME=DEC
ED make it character based
sequence so I have
1972/01/03 23:15:06.238744
What I'd like is
2 days 23:15:06.238744
I can calculate the date difference by hand (in C based off of the
character representation of the date) of course. Unless someone knows of
a nifty method to get the elapsed number of days from the data that I
have?
