Re: Call a RPG program from a CL, decimals error

Hmmm - guess I think that is needed only when you know you'll be doing a call from a command line or with literals - even there, you can always use the hex value that you need to pass.

And this might be useful when doing kind of generic stuff - but I'm all for matching caller and callee, as has been discussed here many time. And I'm not sure it's always best to use 15,5 for everything.

Vern,

Yes - but I was specified "best" as in best practice ...

Hi John

The 15,5 is needed if he passes numeric literals - he is passing a
declared variable, so it is not needed here, at least as far as I know,
which ain't far these days.

The lengths of your parameters do not match.

Also its best to specify numeric parameters in this case as 15,5 - i.e.
length 15 including 5 decimal places.

Hi this is the definition in RPG, is correct?
C *ENTRY PLIST
C PARM P0S9NN 309
C PARM P0S9NP 36

Thank's

Then obviously the definition in your RPG program does not match the
definition in your CL program. Make sure that the definition in RPG
specifies packed, not zoned.
