New and Changed Features
Environment Variables Used by HP Pascal/HP-UX
Example
PASRUNOPTS="E"; export PASRUNOPTS
program prog(output);
begin
writeln(1.0L+200)
end.
The output from this example is 1.0E+200.
The variable is only fetched from the environment once, the first time
that it is needed. Changing the environment will not have an effect on
the runtime library.
