Pointer types

Pointer types may be defined forward as in standard Pascal:

TYPE
  pMyType = ^tMyType;
  … 
  tMyType = BYTE;

Restriction: the forward declared pointer must be found in the current TYPE block.  

A special untyped pointer may be declared as ROM pointer, so if may point to some constant in the CODE memory, like constant arrays:

VAR
  pMyType = ROM POINTER;

• A ROM pointer may occupy a variable amount of bytes, according to the processor's CODE size.
