Cmd Prompt from within CL will not accept blanks

["Allen" <rallen@xxxxxxxxxxx>]

I have a CL program that is executing a command using the
following method

 

CHGVAR   &SHIPITEM) VALUE('10AB56')

 

?CRTORD  ??SHIPITEM(&SHIPITEM)

 

The command prompts fine with 10AB56 pre-loaded in the SHIP
ITEM parameter

 

The problem I have is the user has the option to blank out
the value, but whenever they do and press <Enter> 

the command re-displays with 10AB56 in the SHIP ITEM
parameter.

 

I don't want the user to have to enter *NONE or '  ' 

Is there something in the CMD source code for the parameter
that makes the command accept blanks as a valid value?

                                                           

         PARM       KWD(SHIPITEM) TYPE(*CHAR) LEN(30)
PROMPT('Ship Item Number')           

                                                           

 

Thanks in advance for you help

 

  Allen
