42S local label caching

[Werner]

I seem to remember the ENDs' and global labels' distance fields were coded the same way as in long-form GTOs.
On Emu42, I get the 'Global Span' error trying to add a single byte to a 3578-Byte Prgm containing 1789 NOT lines. I was not going to do that on my real 42S ;-) So there, at least, is no difference with the 41.

Cheers, Werner
