Conflict with XSUB and MBASIC or PIP
-----
Question: Why do I have problems using XSUB with some programs, in
particular MBASIC and PIP?
Answer: Any program, like MBASIC, that uses single character input
or direct console i/o cannot work with XSUB which only supplies console
buffer input.
PIP commands can be given by XSUB but CON: input cannot. Another
problem with PIP is that you cannot exit with just a RETURN since SUBMIT
does not allow blank lines. The following patch will allow PIP to be exited
with either a RETURN or any single character (usually a period) followed by
a RETURN.
