Subject: Late-night problemo!

Don't even look at the time on this message... I've got kind of stuck 
into trying to get BASIC working.

However...

I havew a bit of a problem which I'd appreciate if someone could solve. I 
have put the BASIC ROM in at &8000 as recommended and not yet supported 
ROM paging via &FE30. However, during execution the O/S puts &F into 
&FE30 (is that paging in BASIC? The ROMs are in different places on my 
Beeb) and then (via the instruction at &F17B) does a JSR &8003. This 
causes my emulator to report a non-existent instruction - opcode &1F. 
I've had a look at the BASIC ROM and &1F is indeed the instruction at 
&8003. Just to make sure it wasn't my instruction list (which has been 
known to be a bit dodgy in the past!) I checked up with ADT on the Beeb. 
It reports &1F as being a non-instruction too.

Where have I gone wrong? There is no way (as far as I know) that location 
&8003 could hold anything other than &1F bearing in mind that BASIC is a 
ROM. Help! I'm going to bed before this drives me up the wall!
