Crash printing unset variable in 2.09 RC 3
Boot NextZXOS 2.09 RC3 and run this command:
1 LAYER 1,2: PRINT CHR$ 30;w
A diagonal pattern of screen corruption appears, followed by a lockup or reset once a key is pressed.
Same happens for LAYER 2,1 and 1,1 and lores 1,0 but not LAYER 0. CHR$ 31 fails likewise, as does CHR$ 16, INK.
This seems to be a reversion to a bug SNG previously reported when testing 2.08.
The new repro is even simpler. Any uninitialised standard variable e.g. a$ or oops has the same effect as citing w at the end of the line.
