RE: Passing numeric fields to COBOL program -- MIDRANGE-L

Dean, I was looking for something else and found the
following in the option for CRTBNDCBL, I think we have the
answer.
 

  *NOCHGPOSSGN

      Hexadecimal F is used as the default positive sign for
zoned and       
      packed numeric data.  Hexadecimal F is the system
default for          
      the OS/400 operating system.

 

  *CHGPOSSGN

      Hexadecimal C is used as the default positive sign for
zoned and       
      packed numeric data.  This applies to all results of
the MOVE,         
      ADD, SUBTRACT, MULTIPLY, DIVIDE, COMPUTE, and
INITIALIZE               
      statements, as well as the results of the VALUE
clause.
