Hello,

When I'm in debug and eval the pointer of the multi occurrence DS and occurrence one and get different pointer value (see below). Is this normal?

EVAL %ADDR(MCRADD)
%ADDR(MCRADD) = SPP:CFFC819861042450
EVAL %ADDR(MCRADD(1))
%ADDR(MCRADD(1)) = SPP:CFFC819861041F50

The %occur() BIF or the OCCUR op-code can be used to set the ocurrance of a MODS. When the occurence is set to 1, the addresses should be the same. When the occurrence is set to 2, then %ADDR(MCRADD) shoudl equal %ADDR(MCRADD(2)). When the occurence is set to 3, then %ADDR(MCRADD) should match %ADDR(MCRADD(3)) and so on...


If you're passing the data to a subprocedure by pointer, make sure you set the occurrence to 1 before getting the address that you pass.

A much better alternative is to use data structure arrays INSTEAD OF multiple occurence data structures. Then you can declare the array on the prototype (instead of a pointer) so that it'll always be passed correctly.
