[M100] BASIC trick

[Peter Vollan]

Running the code to send commands to a laserdisk player, I got a
"return without gosub" error. It seems that a limitation of the model
100 is that if you gosub to a subroutine, and then gosub again, it
will forget that it is it in a subroutine, and not understand the
retrurn statement. This is obviously a mistake, but it could be put to
good use. If I am correct about this that is.
