KEYDEF   - Definitions for keys in XCRT
MATH     - Unit for several math functions
MISC     - File exists, timer, and a few miscellaneous things
MOUSE    - Mouse unit
STRINGS  - Some string manipulation stuff
XCRT     - Extension of CRT graphics, makes your life a lot easier
XGRAPH   - Saving/recalling graphics images, cool drawing routines,
           fractal line drawing, and more

Note: some of the routines may look very familiar - occasionally I
incorporate a few procedures and functions I find particularly useful
into my units.
