- This is a simple list of various variables as defined in the
- appendices of the RISC OS 3 PRMs. Some of them are system variables (often
- code variables, which cannot be modifed); others, particularly the App$...
- variables, are suggested variable names applications should use if they need
- such a variable.
- At one point VarEdit will know about all of these (it already knows
- about $Dir and $Path), and tell you about it. (Wishful thinking!).
