AS400 Commands -dependencies between elements

[diego acevedo <diegomacevedo@xxxxxxxxxxxx>]

Hi everybody:
  I'm trying to create a command like CHGDTAARA one where there is a parameter called VALUE that consists of three elements: a start position, string length and the value; this parameter shows *ALL as a default value wich means "starting at first position and max length assigned (2000)", but if I want to enter a different value into the first element (starting position) and none of the second (string length) I want to send a CPD0072 message just like CHGDTAARA command does.
   
  I tried to use de DEP (dependencies) statement but is not working because both elements belongs to the same parameter (e.g: they has the same keyword)
   
  Could anybody help me with this?
  Thank you very much
  Diego Acevedo
