Help! I am trying to rewrite an old Dos 3.3 Applesoft program and the darned
thing gets stuck in several places. I need help in converting the following
from old 3.3 to ProDos:
the "&" sign - I know this is a call, can another be used?
the "& BELL" to ring the bell
I get an "NO BUFFERS AVAILABLE" when I try to run it. Can I type "FREE"?
How do I convert "PRINT CHR$(4);"BRUN CODE" when CODE is the program I want to
run?
How do I load binary files? In 3.3, it was "PRINT CHR$(4);"BLOAD WHATEVER"
How do I type the prefix for the disk on line?
And probably the best question of all - Is there some publication that I can
get that will explain the above? Specifically the marrage between ProDOS and
Applesoft? One that will tell me about all the ins and outs of basic
programming with ProDOS?
Thanks in advance for the time and effort of a response...

As far as Applesoft is concerned, "&" is just a command that jumps to $3F5. There must be a binary file with your program containing some machine language utilities. >the "& BELL" to ring the bell That would be part of the abovementioned binary file. You could probably just "PRINT CHR$(7);" instead. >I get an "NO BUFFERS AVAILABLE" when I try to run it. Can I type "FREE"? NO BUFFERS AVAILABLE probably means you're trying to BLOAD (or BRUN) something at an address that is already in use by BASIC.SYSTEM. This is probably the machine language "&" package. Under BASIC.SYSTEM you can't just move HIMEM down the same way you could under DOS 3.3. >How do I convert "PRINT CHR$(4);"BRUN CODE" when CODE is the program I want to >run? >How do I load binary files? In 3.3, it was "PRINT CHR$(4);"BLOAD WHATEVER" These BLOADs and BRUNs shouldn't need modification, except as required by any rearranging of memory usage that you need to do. >How do I type the prefix for the disk on line? BASIC.SYSTEM is designed to behave like DOS 3.3 *until* you use the PREFIX command. You can still use ,S and ,D options to access devices by slot and drive. >And probably the best question of all - Is there some publication that I can >get that will explain the above? Specifically the marrage between ProDOS and >Applesoft? One that will tell me about all the ins and outs of basic >programming with ProDOS? There's a book called _BASIC Programming With ProDOS_ that would be immensely helpful. Addison-Wesley. There are no doubt other books, and back issues of Open-Apple/A2-Central are always good. >UUCP: {nosc, cacilj, sdcsvax, hplabs!hp-sdd, sun.COM} > ...!crash!pnet01!pro-nsfmat!pro-pac!tomj >ARPA: crash!pnet01!pro-nsfmat!pro-pac!tomj@nosc.MIL >INET: tomj@pro-pac.CTS.COM - BITNET: pro-pac.UUCP!tomj@PSUVAX1 --Dave Lyons, Apple Computer, Inc. | DAL Systems AppleLink--Apple Edition: DAVE.LYONS | P.O.
