Jim,
If you can modify the program actually setting the file equation, you could
also have it do a SETVAR actualdev "xxxx" and query this variable in the other
program.
If you want an excuse to play with some of the posix tools, you could do
something like:
RUN SH.HPBIN.SYS
export shvar=\
`callci "LISTEQ" | \
grep "SYSTEMLP" | \
awk -F= '{print $2}'| \
awk -F\, '{print $1}'`
callci "SETVAR ACTUAL_DEV \"$shvar\" "
exit
This returns ACTUAL_DEV="LP" from the original file equation:
FILE SYSTEMLP;DEV=LP,1
You may have to tweak the awk's: The first one returns everything
after the first "=" (assuming there isn't a second)"LP,1"
The second returns everything before the first "," or "LP".
Hope this isn't overkill.

Subject: FFILEINFO and Device Number
I have a program that sets all kind of file equations for an application.
Other (sub)programs are then called and they use these files that were
equated to various files and/or printers. I need a way to find out
which printer (actually, I want the device from the "DEV=" clause on
the file equation) the file was equated to in the main program from
one of the subprograms or from a child process. I think FFILEINFO
will give me what I want, but I'm not sure how to get it.
FFILEINFO ITEMNUM 6 returns the Logical Device Number, but for spooled
files, "the LDEV is a virtual device number that does not correspond
to the system configuration I/O device list", so I don't think that
will work.
FFILEINFO ITEMNUM 50 returns the "Real device number of the file",
whatever that is. Could this be what I want?
As always, any advice or help is appreciated. BTW, I want the printer
device number because we just got network printing up and running for
our LJ4050N's (way cool! Thanks, HP!) and we can "compress" the
printing from 6 LPI to 8 LPI, so these printers can have more lines
per page than the standard impact-type line printers. So I would
like to be able to "sense" the printer being used and adjust the
page length accordingly.
