Re: [MI400] API QTERTVPV - retrieve OPM pgm variable in debug

["Bruce Vining" <bvining@xxxxxxxxxx>]

The receiver variable has much more information in it than just the
returned program variable value.  Try this instead:

d* allocate much larger receiver variable
d rtnval         ds         1000
d* define returned length of variable value (see API documentation for lots
of other things returned)
d   VarLen              37    40i 0
d* define standalone field for variable value
d Value           s             10

and then after the API call:

c* get the variable value
c                     eval      Value = %subst(rtnval:253:VarLen)

For ILE program debug you may want to look at the Submit Debug Command API.

Hi. I am trying to set up a simple debug error handler and am using API
QTERTVPV and am having problems getting it working 100%. The code below
runs as errcode = blanks after the procedure, but the value of RTNVAL
should be the current library and it is all reverse image blanks... Does
anyone have a fix.. Is it a problem with my receivervar/lengthofrec
definition...

Also is there a hidden ILE retrieve pgm var API that I can use.. I see one
for all variables, but for what I need in this simple error handler that is
overkill. I have looked on all search engines and no one is using this API

Thanks in advance
Dave
