Simple method of including a file that bypasses macro expansion

[John Allsup (M4)]

Hi,

 

I am relatively new to m4, but can't seem to find an equivalent to include that bypasses macro expansion.

 

Suppose file 'a' contains

  hello world

and file 'b' contains

  goodbye world

and in my m4 I have defined

  define(world,and).

I a macro which I will call 'oinclude' such that

  include(a) oinclude(b)

expands to

  hello and goodbye world.

Is there a simple method?

 

Thanks,

 

John
