I am using mainframe FOCUS version 7.3.5.


XYZ,PQR are sequential file.
1) Can we have READ syntax inside the MODIFY command.
e.g MODIFY file XYZ
on match hold a b c d
on match compute
READ file PQR
on match update a b c d
end

2) How to retain the values of variable inside the MODIFY syntax ?
from above example i want to retain the value of a b c and d after coming out of MODIFY syntax.
but currently i am unable to retain the values once i come out of the MODIFY syntax.
can we pass values to the variable used in MODIFY syntax from outside ?

3) in PQR file i have four value in different rows. How can i read the values one by one untill the end of file?

Mukund,

This is a little more than you should expect from this kind of forum.

Your best course of action is to get some training or buy some specialist assistance in.

I don't think that you'll get a MODIFY course but you could use the newer technology - MAINTAIN - instead. I would still recommend a training course though. It will stand you (and the company you work for) in good stead.

You state XYZ and PQR are sequential files.
You can't MODIFY a sequential file. You can only modify non-sequential files, such as a focus database or a relational datasource.
Using modify you can READ a sequential file, using the FIXFORM statement.
You can HOLD data only by storing it into a non-sequential data file using INCLUDE/UPDATE comamnds.
OR you could use the TYPE ON ddname command to write the fields out to a sequential data stream identified to the Modify by using the FILEDEF statement.
I agree with Tony, this is all a bit too much to expect from the forum, and I also agree with his remark to use MAINTAIN instead.

Minimally, please read the chapter on MODIFY in the manual. Your syntax is totally wrong. You would spot that in a New York minute if you just at least read up on MODIFY in the manual.

If these are flat file, you may be looking for MATCH logic instead of MODIFY.
