A83: Re: 3 bits free in symboltable entry? [83]




They are actually used, but not that much.  If I remember correctly, one is
used for equations (to determine whether they are currently enabled or not),
and another to keep track of which variables are selected in the link
screen.  I'm not sure about the third.

It is possible to use these for a folder system.  This is what the Ion
folder module does (though MirageOS uses a different system, which is
apparently more like the 86 method).  The is the values in these bits are
reset by various things, and thus you may get some programs moving around in
folders when you don't want to :)
