IO.equ
IO.equ has equate statements that give readable names to the physical port addresses of peripherals for 485/486
IO.equ can be included in every assembly by altering the Set a86 parameter
Set A86 = mypath\IO.equ +P64
Because IO.equ contains only equate statements which are evaluated at assembly time and do not generate executable statements, its presence will not affect the *.com program
