I agree.

At present MPE uses the word VFXFORTH ( -- ) as an identifier for use
with [DEFINED] and friends. Below that is a set of constants (one per
system) to identify CPU and operating system. For example, on Windows
  TARGET_386_WINDOWS
returns -1. The reasons for this arrangement are lost in the mists
of time. Given the number of CPUs and operating systems around, the
use of strings to identify these is quite reasonable, e.g.
  s" OSX 10.6"
to identify the operating system and minimum version required.
  s" x86 486 NDP387"
to identify the instruction set and requirements. I really must
explore this for ARM and Cortex - even ARM get confused.

I agree, but when will bigForth (and gForth) get text macros?

Just try it and you'll never go back.
