Excellent advice. Unfortunately, the FAQ articles don't necessarily clearly 
describe what's going on in this case.

Note that submitting a CALL via SBMJOB does not require parms over 32 bytes to 
have any added non-blank characters at the end to prevent garbage nor is a new 
command shell needed. SBMJOB handles character parms just fine as long as 
SBMJOB is (correctly? properly? appropriately?) coded to begin with. Where the 
problem with SBMJOB comes in is with the inappropriate use of the CMD() parm 
when RQSDTA() should be used. Two simple example CLPs demonstrate:

TSTSBMJOB:

pgm

  dcl   &cmdstr   *char  64  value( 'sndmsg hi MyMsgQ' )
  dcl   &xgarbage *char  64  value( 'who knows?????? ' )

  sbmjob ??rqsdta( 'call tstsndmsg parm(''' *cat &CmdStr +
                    *cat ''' ''' *cat &XGarbage *cat ''')' )

  sbmjob ??cmd( call pgm(TstSndMsg) parm(&CmdStr &XGarbage) )

return
endpgm

TSTSNDMSG:

pgm    ( +
         &pCmdStr    +
         &pXGarbage  +
       )

   dcl   &pCmdStr    *char  64
   dcl   &pXGarbage  *char  64

   dcl   &CmdLen     *dec ( 15 5 )  value( 64 )

   call  QCmdExc   ( +
                     &pCmdStr  +
                     &CmdLen   +
                   )

return
endpgm

The first submits the second in two different ways, via CMD() and via RQSDTA(). 
The resulting success and failure illustrate the "real" problem here... of 
course, assuming correct library list, an existing MyMsgQ *msgq, etc.

Also of course, this is not the same issue as with numeric parms; but 
understanding one helps with the other.

It's possible that what's going on in this case is simply using the command 
prompter to enter parm values for CALL without appropriate quote marks.
