Crash when assigning to KEY$

[mengstr]

I didn't realise that KEY was a reserved KEYword (pun intended) so I had a KEY$=INKEY$ in the code which resulted in a hard crash.

Thanks for reporting this! I'll fix the bug for the next minor update. Of course you'll still get a Syntax Error for using KEY in this way, but there should certainly not be a crash :)

Fixed by commit 1db4c83 which will be in the 15.08.4 release.

Thanks!
