Which environment variable cannot be set or modified from UniBasic?
Some environment variables
are read by UniBasic only during startup and
so any changes will have no affect on the current
UniBasic process. The following environment
variables cannot be set nor modified from UniBasic
for the running UniBasic process:
ALTCALL, BCDVARS, FORNEXTNEST, GOSUBNEST, INPUTSIZE,
ISAMBUFS, ISAMSECT, ISAMFILES, LUST, NUMLINES,
PORT, PORTS, PROGSIZE, TERM, VARSIZE and WINDOWS.
