Description:

ST-80 compatibility class.
This may be required when existing code has to be ported to ST/X;
however, it may not be complete and more protocol may be added in the future.
The code here was created when public domain code (Manchester) had to
be ported to ST/X and missing classes/methods were encountered, and code added
by reasoning 'what the original class could probably do there'.

In ST/X, all OS command facilities are found in
the OperatingSystem class; have a look at the getEnvironment protocol
there.
