Hi All,

Quick question regarding the MENUCMD command in MPL:

If I use this command in order to goto (rather than gosub) a menu, can I assume
that Mystic will automatically destroy the context in which the script is
running?

In others words, as the menu has no path back to script (or perhaps it does?),
can I assume that Mystic won't leave a zombied script behind?

As always, all advice gratefully received.

Not worry.

Mystic doesn't appear to honour 'GO' from inside an MPL script (probably for
good reason), so this question is somewhat moot.

Mystic will not switch menus until you exit the script on your own.

So if you have a simple MPL like:

Begin
MenuCmd ('GO', 'main');
WriteLn ('Hello! |PA');
End.

Mystic *will* honor the GO command, but it will not take you to the main.mnu
until after the script, so you'll see the Hello and the screen pause then it
will load main after exiting.

.... Shortcut: longest distance between two points

Optimization hinders evolution.
