I made it when I saw that asm includes would no longer be provided by guigfx.library's author... So you can be assured that this script works quite well for converting guigfx.h, at least ! ;)

Features:

• Works, most of the time (or should it, at least)
• Doesn't handle structures inside structures, ie:
  STRUCTURE structure,0
   STRUCT blabla
  will never be generated. You will have to do this yourself.
• RexxDOSSupport.library required !

Download it:

• H2I.rexx

Then don't forget to read the doc which is included in the script.
