Re: Having the same file open twice in an RPG program

Hi, Buck, and James:

I was going to sugest something like that, but then I thought that it was "too old school" and waited to see others reply with more modern solutions. :-)

I can't recall ever being able to have the same file open twice in an
RPG program, other than by having two different LFs on the same PF.

I'm pretty sure we used a pattern like this on S/38:

FFOO IP
FBARA IF disk
F          rbar krename rbara
FBARB IF disk
F          rbar krename rbarb

To compile:
ovrdbf bara tofile(bar)
ovrdbf barb tofile(bar)
crtrpgpgm

To execute:
ovrdbf bara tofile(bar)
ovrdbf barb tofile(bar)
call...

My memory isn't what I remember it to be. I can't find the S/38
manuals online anymore, and the oldest reference I have is the V4R4
Softcopy circa 1999. I can't run Library Reader for Windows in Linux
or Windows 10, so I had to spin up a VM to run that venerable 16-bit
application. Incredibly, Microsoft activated my equally ancient copy
of Windows XP over the phone. So now I can read the V4R4 RPG (not ILE)
manual and verify that my memory isn't a total loss.
