How to handle TYPE(*PNAME) in command source definition

Question

1. How to make a TYPE(*PNAME) parameter be:

   • Required
   • Have a Default value
   • Have an initial length of 10

2. How to handle increases in the length of the prompted field,

   • The length of a prompted field of the type *PNAME can be increased with "&".
   • RPGLE needs to be the command processing program (CPP)

Example, command source definition:

PARM   KWD(PCML) TYPE(*PNAME) LEN(10) MIN(0) DFT(*MYDFT) SPCVAL((*MYDFT)) PROMPT('PCML Input path')

Answer 1

• Use the MIN option to make the parameter required.
• Use the DFT and SPCVAL options to specify default and special values.
• Use the LEN option to specify the maximum length.
• Use the INLPMTLEN option to specify the initial length.
• The command processing program must be defined to accept the maximum length.
