This is a common problem and is covered in the FAQ-O-Matic at midrange.com:

Best answer on another post:

Those you should definitely read.

The quick answer is CL doesn't know how long the RPG char is supposed to be,
and it defaults characters to 32 bytes.  Your string is shorter than 32 bytes
(the contents get converted to a literal and it ignores the spaces) and so
CL pads the literal with spaces to make the 32 byte string.  The extra stuff
you are seeing are the 7 bytes of memory after your passed parameter.

To fix it, pass 40 bytes and make sure the 40th byte is not blank.  Then CL
will pass 40 bytes since it is longer than the 32 byte default and your RPG
program sees what you expect it to see (the 40th byte being ignored by your
RPG program).

dcl &parms *char 39
dcl &parmstmp *char 40
  display prompt screen, get various parms
  combine parms into var &PARMS
chgvar &parmstemp (&parms *cat 'x')
call WO11JQ0 PARM(&PARMSTEMP)
