Hi!
I downloaded BASIC 128 from DATA BECKER ('think it's Abacus compiler?).
But when I mount diskimage and load&run program it shows ERROR 20: COPY PROTECTED...
...so my Q is simple:
HOW TO REMOVE COPY PROTECTION AT DISKIMAGE OR TRANSFERED IMAGE TO REAL 5,25" DISK ????

Thanks for every answer.

From where did you download it?  When I stop traveling around, I'll settle down and send Lance a .d64 copy of Basic 128 for him to post here.

In vice turn off the true drive emulation and the program will run.

Well, I'm still travelling around (right now in the Seattle area but a return to California tomorrow), but I now have the .d64 of Basic 128 to pass around.

Now this is interesting.  I also got the error message even though True Drive was enabled.  You also need to uncheck "Use IEC Device".  Then the program "worked"

I wrote a simple program:
Code Select

10 DO:?X:X=X+1:LOOP

and saved it as "INTEGERS.PRG"

As you can imaginge, these program was only 1 block long.  Then I ran "BASIC 128" and selected option 1: optimize / compile.

The result was a 38 block program!!  I loaded the program and typed LIST.  It did the old 64 trick of deleting the listing and replacing it with a logo:
Code Select

1985 BASIC 128 V1.02


Umm, okay.  Now let's RUN.  And the output?
Code Select

BREAK
    PC   SR AC XR YR SP
; F4C02 30 4C FF 00 F8


Am I missing something?  Is VICE broken somehow?  Is the software a joke?  Is my program too simple?
I'm kupo for kupo nuts!

I can't help you with VICE (because I only use real Commodores for the most part), but the software is no joke.  Abacus' Basic 128 (which I believe is the same as the Data Becker Basic 128) is an excellent compiler.  FWIW, I copied my original disk with the Maverick disk copier and got a fully-working back-up copy.

              Lance, where did you put that .d64 of Basic 128 I sent you?

Abacus was the U.S. licensee for Data Becker, so yes, they are the same.

I just lost an eBay auction for a copy with manual. My bid was pretty high, too. :(

Hydro, a compiler attaches an 'engine' that runs the compiled program. It stays the same size no matter how big your program is. You still get a speed advantage, but you won't get a smaller size until your program is about twice the size of the engine. Since you compiled a one-line program, you can probably figure on those 38 blocks as the compiler's overhead.

Heh, give me a little time, Mark, and you will find something in your postal mail.

     I've never known disks and photocopies that eat.  ;)

Just wanted to confirm that it is working with Vice 2.x with true disk emulation enabled. It is needed as the protection mechanism is accessing (reading) disk drive directly for a security check. This is why Maverick - being a nibbler - is able to make a working copy.
