Yes and no.

Remember, you're dealing with stream files. There's no concept of
"first record".

The only way to add bytes to the beginning (or middle) of a stream
file is to create a new file from the bytes in the existing file
inserting the bytes you need where you need them.

It doesn't matter what platform/language you use.

Editors like notepad or EDTF copy the entire stream file to a buffer
(or temporary file) then copy it back out when you save. Your program
will need to do basically the same thing.

I am using ExtProc('write'), ExtProc('open'), etc to create a text file in
the ifs. I was wondering if I can us this type of logic to update an
existing text file. I need to update the first record of the text file with
summary information.



Can this be done? Examples?



Thanks.
