Following compiles with error: "illegal instruction <<include1 "B.asm">> in "A.asm"

(the code is in the attachment)

File "main.asm":

Code:

macro include1 name { 
  \include name
}

include1 'A.asm'

File "A.asm":

Code:

include1 'B.asm'

File "B.asm":

Code:

include1 'C.asm'

File "C.asm":

Code:

db 1

In order to be compiled, the macro in main.asm should be:

Code:

macro include1 name {
  macro include1 name2 \{
    macro include1 name3 \\{
      \\include name3
    \\}
    \\include name2
  \}
  \include name
}

This is normal. You can't have a recursive macro unless you define another macro inside the primary macro. See the allow_nesting macro in win32ax.inc for an example. Also see my includeonce macro for another example.

Code:

match =files@included,files@included{

      macro nest_includeonce\{
              macro includeonce path,[instr]\\{\\common
                  file@include equ path
                       match head path tail,files@included\\\{file@include equ\\\}
                 match head path,files@included\\\{file@include equ\\\}
                      match file,file@include\\\{
                         files@included equ files@included path
                              nest_includeonce
                            include file
                                purge includeonce
                           irp i,instr\\\\{i\\\\}
                    \\\}
                \\}
  \}nest_includeonce

        macro show_included\{match x i,files@included\\{irps j,i\\\{display \\\`j,13,10\\\}\\}\}

   files@included equ x

}

Or you could have look at my implementation for a yet another one example. Smile
