RE: 3000-char CL parm padded with hex zeros

Dan,

If you change the interface to the program into a command you can make the parameter a varying string where the first two bytes will tell you how long the string is and that way you won't get garbage at the end of the string. Also, you can pass this directly to a RPG program as a Varying Length Character field.

Thanks,

Marvin

subject: 3000-char CL parm padded with hex zeros

CL program PGMA submits CL program PGMB, passing three parameters: A10, B10, C3000. The latter field is a 3000-char variable that PGMA builds.
Before the SBMJOB CMD(CALL PGMB PARM(A10, B10, C3000), I have a DMPCLPGM that shows that C3000, at the end of the content PGMA puts in it, is padded with blanks (x'40'). However, upon entry into PGMB, the padded blanks convert to hex zeros (x'00'), and this creates a problem when I use the %trim built-in. I.e., nothing gets trimmed.

Is this the expected behavior? I vaguely recall issues where garbage shows up in parameters when passing a literal that is shorter than the receiving parameter, but in this case, both programs have the same variable definitions for the three parameters.
