The files in this directory are support files
for ARMForth.

Editor - conventional Forth line editor words
GraphWords - words which facilitate use of OS graphics features
OSConsts - SWI names and numbers as constants
OSDefs - friendly interface to SWIs.
Strings - ARMForth way of implementing strings
          (this was an experiment I think - ARMForth
           already has built-in strings)
Windefs - a useful set of words allowing window
          manipulation
          (there's a bug in the demo at the end
           of the file - when you try to close the
           ARMForth window the system sometimes
           freezes - haven't investigated this yet)
XOSDefs - OSDefs with X bit set
