     There are several ways to avoid having to mess with a disk SAVE/LOAD. The
simplest approach may be to DIM your array to some value large enough to hold
as many X() vars as you may ever want.

     Then you can just keep track of how many valid X() vars there and make all
array scans, checks, etc. dependent upon that number.
