[Coco] Reading/Writing Model I/III/4 Disks on a CoCo

[Luis Antoniosi (CoCoDemus)]

Gene I tried this:

OPEN #in,"image.dsk":READ
OPEN #out,"/D0@":WRITE
FOR t=34 TO 0 STEP -1
FOR s=17 TO 0 STEP -1
SEEK #in,(t*18)*256.
GET #in,sector
SEEK #out,(t*18)*256.
PUT #out,sector
NEXT s
NEXT t
CLOSE #in
CLOSE #out

It gives me error when T is higher than 34!

Why does it copy backwards ? Because I want to write the LSN0 at last.
Maybe the problem is the SEEK and not the GET/PUT. I didn't go further, I
made an asm routine and solved my problem.
