I have a file that is present in the following format
Header Record
Detail Record - 1
Detail Record - 2
Detail Record- 3
Trailer Record

In the Trailer Record I am taking in the count of total number of records present which in the above case works out to 3.

I have a requirement to update the number of records on file in the Trailer record which i am completing by making use of the IFTRAIL and TRLUPD functions.

I have my sortcard as below

Select all

OPTION COPY
OUTFIL FNAMES=OUT12,
    IFTRAIL=(HD=YES,TRLID=(1,2,ZD,EQ,+9),
    TRLUPD=(14:COUNT=(M11,LENGTH=4)))

Now, my problem is that the Output COUNT that appears should be an Signed value.

For Example: if the count of records comes out to 4 then i want it represented in the Trailer as 0004F. I want the Sign bit as well to show if it's positive or negative. I realise that the count of records will always be Positive but i still have to display that Sign bit.

Please let me know how this can be achieved in TRLUPLD part itself.

Thank You,
Healy

You're using an "edit mask" (the M11) to format your count, so it is always going to be human-readable (F not C). Look at the option for COUNT in the documentation.

I did look up the manuals but i couldn't find any mention of using COUNT in a way to display a signed Value. I realise that i am using an editing Mask pattern M11 but that is what i have to replace in order to get the Signed Bit.

Select all

COUNT=(TO=ZD,LENGTH=4))

Thank you for your Help Billy.

The solution provided by you worked but i had to make a slight modification to it to obtain the Signed Bit.

Select all

COUNT=(TO=ZDC,LENGTH=4))

Thanks,
