Definition
ASSIGN makes it possible to define absolute addresses for symbols at LINK time.
The absolute address associated with the vcrriable-name is specified in address,
which should be an absolute 20-bit memory address that conforms to PL/M-86
notation. The
variable-name
is internally defined as a PUBLIC symbol.
Notes
• This control is particularly useful for memory-mapped I/O.
• If the
variable-nam€~
has a matching public definition in another module, the
public definition in that module is flagged as as duplicate. Whenever a reference
to the variable-name occurs, the variable defined in the ASSIGN control
governs.
• If multiple ASSIGN specifications are provided in one LINK86 invocation, all
will be effective (not only the final entry).
