The Reader is Warned!

The pages which follow have been lifted more or less verbatim from the documentation for the Unix-based implementation. Anything with obviously operating-system dependencies may possibly work in the console mode we have today, but is most unlikely to work in future builds of the Windows version of A+. In the current build, several 'advanced' system functions (such as _fmt) appear to be missing. A search will be instituted!
