No - there is no EXTEND mode - too
early.
Can I suggest that you use ISAM mode instead for this file if
needed create a simple key if there is no field that you can use
say starting with 1.
Then OPEN I-O, then all WRITE statements for a new record will
work with the added benefit if also using REWRITE if you need to
update an existing record.
See the documentation from Jay regarding the use of ISAM type
files with Cobol for how to do it.

Hi folks.
So I'm trying to append records to an existing dataset with
COBOL... wich should be quite straight forward: OPEN EXTEND
MY-FILE
But it seems the compiler does not support that opening mode.
I took a look at the 1972 IBM book I use as a reference for the
included compiler and, at OPEN clause, section (very brief one...
so maybe not a comprehensive guide with not all options covered),
I see that it only mentions INPUT and OUTPUT, no EXTEND
whatsoever.
So while I believe that it is indeed possible, the thing is that
there must be for sure a way to perform such a fundamental
operation, even with this compiler.
As anyone a clue? Am I missing something?
Thanks you.
Cheers.
Alex.??
