;****************************Public Macro************************************
;
; The following sections contain calling-convention related macros for:
;
; PUBLICP Func,N
; to define a public label
;
; EXTRNP Func,N
; to define a external near label
;
; LABELP Func,N
; to label an address as a routine entry point
;
; cProc Func,N,ArgList
; to declare a routine header
;
; ProcName Name,Func,N
; to rename a function Func to Name. Using it in conjunction with
; normal function declaration (with the new name) will solve an error
; caused by a long parameter list routine that exhausts page width.
;
; cRet Func
; to return from Func routines (declared with cProc or ProcName.)
;
; endProc Func
; to declare the end of routine (declared with cProc or ProcName.)
;
; endMod Func
; to declare the end of module with an entry point at Func (declared
; with cProc or ProcName.)
;
; cCall Func,ArgList
; to call to a routine--Func--with the arguments pushed on the stack
;
; ptrCall Func,ArgList
; to call through a pointer with the arguments pushed on the stack
;
; MovAddr dest,Func,n
; to move the address of the routine--Func--into dest.
;
; Note that for the standard calling convention all the function names,
; Func, are automatically converted to Func@N where N is the number of
; bytes in the argument list.
