A very effective Applesoft memory test

Here's a simple-but-effective Applesoft program that rigorously tests main memory.

In its first pass, the program uses Applesoft's pseudorandom number generator to fill addresses 4096 through 49151 ($1000 to $BFFF).

In its second pass, it resets the pseudorandom number generator and computes the same sequence again...but this time it compares the values that were previously stored in memory and detects any that don't match.
