Subject: Am I saving or loading 1 byte too many....?

I always use the "+" alternative, eg.

*SAVE xxxx 3000+1000

To me, that would save exactly &1000 bytes from and including &3000 up
to &3FFF, which is the &1000th byte.

There isn't a *LOAD xxxx 3000 4000 syntax, it's *LOAD xxxx 3000 which will
load xxxx starting at &3000 and continuing for the full length of file xxxx.

Best wishes,


Ian

Hi folks.

Okay, this is giving me a headache, and I can't decide which way round is 
right, but I'm sure you guys will flog me and tell me a definative answer.

*SAVE <xxxx> 3000 4000

Should that save the actual byte at &4000 or not? Or should it only save to 
&3FFF? I suppose if it saves &4000, the filesize would be &1001 wouldn't it, 
as it's actually written &1001 bytes, or is it &1000, as &4000-&3000 = 
&1000?

Similarly:

*LOAD <xxxx> 3000 4000

Should that retain the old value of &4000, or overwrite it with the last 
byte of <xxxx>

Thanks. Mark.
