Re: How do I pass a packed numeric valid into a called RPG program?

I would assume so - but it is pretty easy to check.

If (say) the value 9 is passed with a definition of 7,2 then the command processor has to do work to align and store the value in the correctly sized variable. No reason to suppose that a char field would be any different.

If I have a parameter with a length of say 100 - in the past we would need to put something in position 100 to ensure the entire parameter length was passed.

Does specifying the length on the call negate this requirement ?

So instead of

Call pgm001r parm('this text is less than 100 characters so I have an asterisk in the 100th byte *')

(Please note this is an example and I did not count the full 100 characters!)

We could use

Call pgm001r parm((('this text is less than 100 characters so I have an asterisk in the 100th byte') (*CHAR 100)))

Besides using data types directly on the call command like this
CALL PGM(RPG_PGM) PARM((31 (*DEC 10 2)))

You can also declare your parameter in your RPGLE code a package decimal
(15.5) this is what the command processor by default converts values to.

Then i look like;

CALL PGM(RPG_PGM) PARM((31)

...
pi *n;
p1 packed (15:5);
end-pi;

I have seen it done but never used it. How would I call a RPG program
passing packed numerics from the command line?



Call RPG_PGM parm(31)
