Re: why are my parameters sharing same memory?

David,

Sounds like a parameter mismatch....

But it's kind of hard to tell what you're doing given the snippets of
code you've posted.

Why %subst() on error? Why isn't error a data structure?

And why are you only pulling 6 bytes for what is a 10 byte value?
ErrorPgm = %SUBST ( error : 1 : 6 );

Hi all,


I can't see why ErrorMsg and ErrorPgm are dependant on each other.
When ErrorMsg  or ErrorPgm is modified, then the other parameter is also changed.


P Main            B
D                 PI
D ErrorCode                           LIKE ( ERRCD )
D ErrorPgm                            LIKE ( ERRPG )
D ErrorMsg                            LIKE ( ERRLB )

D error           S                   LIKE( ERRMG )

IF NOT MySP ( error );

  ErrorCode = %SUBST ( error : 8 : 4 );
  ErrorMsg  = %SUBST ( error : 14 );
  ErrorPgm  = %SUBST ( error : 1 : 6 );

ENDIF;


Debugging, if I change ErrorPgm, then positions 11 to 20 in ErrorMsg change.


error   = 79A
ErrorCode       =  4A
ErrorMsg        = 73A
ErrorPgm        = 10A


Thanks.
