First read of masterfile :

Second read of masterfile

Chain to detailfile still reads file in lib1 because still open

[W]e are on V5R4.

I can think of a way of doing this, but it isn't particularly pretty. Nor is it tested, but I've done something similar before. You could define a different F-spec for each library's detail file, renaming the record formats and prefixing the fields as appropriate.

Fdetail IF E K DISK EXTFILE('LIB1/detail')
F RENAME(detail:L1det)
F PREFIX('L1')
Fdetail IF E K DISK EXTFILE('LIB2/detail')
F RENAME(detail:L2det)
F PREFIX('L2')

Then, your read logic would look like
do %eof(masterfile)
Read masterfile
select
when library = 'LIB1'
chain L1Det
when library = 'LIB2'
chain L2Det
endsl
Myfield = detail file field

Hope this helps,
