why are my parameters sharing same memory?

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.
