This is weird - just plain won't run the code?

[Darkstar]

I'm going to file this under "weird"

It works for me now as well. I don't actually own a real spectrum I was, and still am, running it under spectaculator 8.0. It crashed last night each time. Today, it behaves....

Now I'm really baffled.

Could it be you were running it on a non standard mode (e.g. +3, +2A, another clone)??

Maybe. Not recoverable now. But it's a thought - perhaps it was left in an odd mode!

I have had this problem and as it turns out the compiler did an "push hl" in the start up code just after the beginning RAND USR address or ORG, do not know why but there was no reason for it to be there and that is all I know.
