Re: Passing unwanted parameters

Simon,

Yeah, I'm aware that the DSPLY is showing the variable rather than the data
area - I was actually stepping through in debug and getting a command line
to check the value of EXTRAPARM (as well as check its locks). The DSPLY was
left from earlier testing - sorry, a bit of a red herring.

My puzzlement is that I don't know where the EXTRAPARM data area is being
created. I assumed it was in the initialization (effectively in the *INZSR),
but when I created an RPG/400 program and compiled it with GENOPT(*LIST), I
couldn't see where the data area is either created or retrieved. Mind you,
things may have changed between RPG/400 and RPGLE (and indeed, my MI may be
a little rusty), but I'm damned if I can see where the program creates the
data area. Maybe the RPG runtime creates it...

In any case, we've all gone rather off-topic now, haven't we? My bad....

Rory.

p.s. My code:

1) You're releasing the lock on the data area when program 1 does
the OUT operation.

2) You're displaying the program value of ExtraParm not the data
area value so you won't see the change made by program 2.

3) Because you issue a return with LR off the program initialisation
is not performed on subsequent calls so the content of the data area
is not read in at program start. You'll see whatever happened to be
the last value of program variable ExtraParm.
