Re: Problem with duplicated file names

If performance is very important, you can try to use the c file io
function (_Ropen,...) to do what you needed.

If performance is not import, you could create a sub-proc to reopen the
detail file when needed, code would look like below:

FDETAIL IF E K DISK extfile(actualDetailFile)
F INFDS(detailInfds) usropn

D detailINFDS ds qualified
D fileLib 93 102

D actualDetailFile...
D s 21 varying

D reopenDetailFile...
D pr
D piLib 10 const varying


/free

Read masterfile
dow not %eof(masterfile)
reopenDetailFile(WhatEverLib);
CHAIN detail file
Myfield = detail file field
. . .
Enddo

*inlr = *on;
/end-free
*****************************************************************
* reopen Detail File when Necessary
*****************************************************************
P reopenDetailFile...
P B
D pi
D piLib 10 const varying


/free

// only reopen the file if the library of the current opened
// detail file is not the same as requested
if detailInfds.fileLib <> piLib;
if %open(detail);
close detail;
endif;

actualDetailFile = %trim(piLib) + '/DETAIL';
open detail;
endif;

/end-free

P reopenDetailFile...

Hi,

A similar problem to the one I had using activation groups but for
reasons I won't explain, I can't use ACTGRP or TFRGRPJOB.

do %eof(masterfile)
Read masterfile
CHAIN detail file
Myfield = detail file field

enddo

One masterfile, several detail files in different libraries. Program
knows which library. Program is batch.

How do I CHAIN to the right detail file, each time leaving the file open
for the next read. Lots of other programs will want to be able to access
any information from the detail file in the same way.

Thanks.
