z80:Directives:USING

Allows access to a module's local labels from the current module. The current module always takes priority, and any modules added through .using are given more priority based on the how early they were added.

Syntax

   .using module

Uses

   .module Main
   _label = 1
   .endmodule
   
   .module Test1
       ld a,_label ; Assembler error.
   .endmodule
   
   .module Test2
   .using Main
       ld a,_label ; a = 1.
   .endmodule
   
   .module Test3
   .using Main
       ld a,_label ; a = 2
   _label = 2
   .endmodule
   
   .module Test4
   .using Test3
   .using Main
       ld a,_label ; a = 2 (Test 3 takes priority)
   .endmodule
