Hi Julian!

I haven't followed this thread very attentive. You are talking about the flags
that one can use for mxalloc? As far as I remember, you just have to check if
Ssystem-call is present - if not, you only should use the Flags 0 and 1:

FUNCTION mxmask
  IF GEMDOS(68,L:-1,0)=-32
    RETURN 0
  ELSE IF GEMDOS(290,-1)=-32
    RETURN 3
  ELSE
    RETURN -1
  ENDIF
ENDFUNC

That was the way that Frank wanted to write into the MiNT-docs. Thomas Binder
said, that Andreas Kromke agreed in adding Ssystem to MagiC when implementing
memory protection.


A happy new year!
