RE: Transfer a 8250 diskette

Commodore BASIC has a hard time will null strings. You have to use the
chr$(n) function.

Subject: Re: Transfer a 8250 diskette

Hi all,

I am still working on the disk transfer.

I first want to try a software transfer by copying the data byte for byte.
I made this small program


10 nm$="8032-700-asc-ns"
20 open 2,8,2,"1:"+nm$+",p,r"
30 open 3,9,3,"0:"+nm$+",p,w"
40 get#2,a$
50 if st=64 then goto 80
60 print#3,a$;:goto 40
80 close 2:close 3
90 end

The program makes a copy, but the file size of the copy is smaller than the
original (Example: original 81 Blocks, copy 79 Blocks)

Is there an error in my program?

The source (8) drive is a 8250lp, destination (9) is a MicroPower 2000
(4040) and the computer is an 4032.

Or is it the difference in floppy formats?

Richard
