I don't know if this will help but if you
write.
PRINT PEEK 23181
PRINT DPEEK 23182
this will print the page and the address of the
last byte used by basic.

Subject: Re: problem with Basic
thanks for tips... it is a REALLY big headf*ck when it happens,
and yes, it`s
something that will usually happen if you code anything above
a certain size so it is a very well known bug. I like the idea of moving it
but I don`t know which bit of the program is at a page boundary (and also it`s
3 or 4 different programs).
Also, with a few of them I can be jumping
around a lot in the code, perhaps i guess as much as 20-30 K away
constantly. perhaps that could also be an issue ?
When your
programs used to show problems with the bug, did they just
freeze the
entire machine up, or crash it/reset it entirely?

I found, that if
it was not running correctly or I was having problems
editing a line, I
would put as the first line in the entire program a

statement.
I found that sometimes by adding a few random
characters, or taking
some away on that line seemed to move the code
around in memory enough
to enable it to spring back in to life again! Not
100% why,
put the paging issue sounds highly
likely.
