Two points. Firstly it's very bad practice to allow anything on your
computer to have a path/file name longer than about 240 character as the
Wimp message system can't handle anything longer than this so all sorts of
programs will crash.

Secondly it's best not to use Basic strings for this sort of thing anyway. A
'string' is just a collection of bytes, and you can put them in an integer
array and access them with the indirection operators rather then the Basic
string functions. That way they can be as long as you like.

Yuk! Those should have been shot long ago. Either arrange your data in a
block of memory and load and save that (much quicker), or if you must save
and load it a bit at a time use BPUT# and GET$# or BGET#. They don't do
everything backwards.
