RE: MODS Likerec

Thank you, Scott, your assumptions are right; this is what I was trying
to do (I am not sure I understood exactly your last sentence, though: do
you suggest using a pointer or something?)

I will start studying and using what Birgitta and Jon advised: array DS.
Hopefully I will make it works.

Hi Florin,

the problem with LIKEREC is that it implicitly qualifies the fieldnames.

I'm assuming you are doing something like this:

D MyMods ds occurs(9999)
D likerec(myRecFmt:*input)

Therefore, you'll have fields named

MyMods.field1
MyMods.field2
..etc..

And file reads will go into

field1
field2
..etc..

And since these are different field names from the ones in your DS,
there's nothing "automagic" going on. If you want the fields to be the
same, stop using LIKEREC. Alternately, read directly into the DS
instead of expecting the fields to match on the I-spec.

This is the idea: I have a subfile populated by the user. I want to
insert some records between already existed records if some criteria

is

met. My idea was to read the entire subfile and to save it to a MODS
defined with LIKEREC(the subfile record name), clear the subfile and
repopulated it one by one record (reading MODS) and inserting, when
needed, the new subfile records.

My problem is I cannot retrieve the MODS. I do an %OCCUR(mods-name) =

1

and a WRITE the subfile record. In this moment, I thought the subfile

is

automagically populated because they have the same field names... but
it's not!
