Subject: Re: BASIC IV: Coded Line Number

Thanks Richard
 
I do not quite understand the reason for having encoded line numbers within 
the program when you have the &8D line number token alerting you that the
three bytes following represent an encoded line number. Why could they not
just have the line number token &8D followed by the line numbers in standard
LSB, MSB format??
 
I looked at the site you sent. In other places there it mentions BASIC V. 
I did not realise there was a BASIC V produced. Do you know who dseigned
and produced it? What improvement did it have over BASIC IV? Do you have
a copy of it? Can it be put on to an EPROM and used in a Master instead of
BASIC IV??
