42S local label caching

[Andres]

And if the distance to the label is too long, you may end up with a "Global Span" error message in the display of your 42S. I don't have the details at hand, but the maximum allowable distance was some 3500 bytes IIRC, which is quite a lot for a machine which had 8192 bytes of memory for programs and data. I suppose that those who expanded their 42S RAM from the standard 8 KBy to 32 KBy may find themselves in this situation from time to time. Once upon a time I took the effort to fill program memory space with hundreds of instructions until I was able to obtain the elusive "Global Span" message, it was not something you would find in normal usage.
