Re: CL Corrupt Parm

Hi Ken,

The CMD() parm was apparently intended to support prompting of structured commands. But CALL does not structure its PARMS(). The result of prompting the CMD() parameter value is a command string that SBMJOB passes into RQSDTA() internally.

Stripping off trailing blanks in the process. That's busted behavior.

But... _exactly_ what blanks are stripped?

Consider this trivial program:

pgm ( +
&p1 +
&p2 +
)

dcl &p1 *char 50
dcl &p2 *char 50

sndmsg ( &p1 *cat &p2 ) kensims

dmpclpgm

return

endpgm

And this:

sbmjob cmd(CALL PGM(TSTSBM) PARM('here is a 50-char string <pad to 50-char>' 'and here is another...<pad to 50-char>'))

When the two parms have blanks added out to the *CHAR (50) lengths defined in the CL program, everything runs fine on my system here. No garbage if I CALL interactively and none when I SBMJOB.

OTOH, if I simply prompt a CALL command and type the strings _without_ quoting out to the proper lengths, the parms only contain the significant characters. Blanks aren't "stripped" or truncated; they simply never existed. Garbage results.

Is that IBM's responsibility? I.e., if I don't supply correct values, aren't I at fault?
