I would be interested in seeing the code too.

RE: work files in qtemp






Hi Vincent,

<snip>
I agree that files in QTEMP can be a pain...however; in my shop we have
a
product called PEEKPLUS  (from BYTWARE).  With the product, we can
"Grab"
control of any job (with permission) and copy those files out of QTEMP.
It
can also see the LDA & insert other commands into the job.  It's a great
'Fire Fighting' tool.
</snip>

You wouldn't believe how easy it is to get hold of another job's QTEMP
objects. In fact you wouldn't believe how easy it is to get hold of 
another
job completely! A while back somebody told me you couldn't
see/manipulate
objects in another job's QTEMP. Well that's a red rag to any programming
bull. :-)

By the end of the day I'd written three VERY simple CL commands (and a
couple of processing programs in RPG) that allowed me to take control of

any
job in the system and then force it to issue any commands I sent it. (I 
had
some fun sending naughty break messages to one of my colleagues, from
the
interactive job of another of my colleagues! Ooh the look on their 
faces!!!
Or sending a program call command and watching their faces as a screen
appeared!!!)

On a practical note...

Once, at 3am I got a call about an overnight finance batch job falling 
over
- a RPG program was trying to use a LF that should be in QTEMP (scoped 
over
the PF there). Normally that's unfixable - have you ever tried to create
a
LF in another job's QTEMP, and scoping it over the PF there? BIG smile 
from
me, cancelled back to the CL, copied the LF into QTEMP of the batch job,
retried the call - 5 minutes later I was back in bed.

The commands I wrote are:
STRJOBCMD - here you specify the job you want to take control of.
SNDJOBCMD - here you send a command to that job. You can send as many as

you
want.
ENDJOBCMD - here you release control.

I still use them when servicing a batch job and debugging it. If I get
to 
a
point where I want to see what's in a file in QTEMP I simply send a 
command
to CPYF it into a production library. I can even amend the data and cpyf
(*replace) it back again. All this while sitting on a break point! Boy 
does
that make life easier.

Anybody who wants the source are most welcome. I'll even post the whole 
lot
on the list if it's something that might be of use to people - but
believe
me, there is nothing to these programs.
