RE: [C400-L] CMD parms

["Ulrich, Kent" <Kent.Ulrich@xxxxxxxxxxxxxxx>]

String argements coming in from a command or a CL program will have a length
equal to the declared length in the command or CL program with no null
terminator.  When returning arguments from a C/C++ program to a CL program
they must be padded to the length declared in the CL program without a null
terminator.  The alternate is to also pass a length and handle the strings
accordingly in both the CL and C/C++ programs.

Hi,

My C program has a string arg which works fine when i do
call pgm 'this is the string'

But I made a CMD interface, so I could:
CMD PARM('this is the string')

Of course the string that gets passed is full of junk at the tail end.. I
can
overcome this with SBMJOB CMD(CMD PARM('this is text')) but how can I call
it
interactively?

BTW I have written a CL wrapper to get/examine the returned arg, and I guess
I could use this to pass the string length or append a \0 at the right
place... but am i overcomplicating this?

NB if this isn't as common as I think it is, my string lengths are 9999 in
the CMD, CL and C...

Thanks,
