I have a question about running an Integer basic program off a hard drive. I have a IIgs with a 20 meg Sider. I want to run an old program called "Mr Calendar" that runs in Integer basic. I put it in subdirectory with basic system and Int.Basic file in the same subdirectory as the basic program. It won't run off the hard drive. I get the message Loading Integer into Language Card No buffer available Break in 210 Does any one know of a way to get this program to run. I have no problem with the program off a floppy disk in DOS 3.3. Thanks in advance, Tim

[can't run Integer BASIC program from ProDOS subdirectory even thought
INTBASIC is there too]
Unless something strange has happened that I don't know about, Integer
BASIC is not supported under ProDOS. See, that INTBASIC file that
works under DOS 3.3 goes into the memory whose address space is shared
by Applesoft, and DOS 3.3 switches between the two with FP and INT.
Since ProDOS already uses that memory, attempts to overwrite it will
probably result in a crash, or a memory protection error if those
sections of memory are included in the system global page memory map
(I don't remember these things too well in my old age).
Anotherwards, it can't be done easily.
Your best bet is to convert that Integer BASIC program into Applesoft
and go from there. Unless the program uses hires graphics or imbeds
raw code in the program load, it shoudn't be much of a problem. On
the other hand, if the program is the size of Apple-Trek, it might be
rather time-consuming.
Another interesting avenue might be to conjure up one of those Integer
BASIC compilers (wasn't there one called FLASH?) and use the
executable under ProDOS.
Wondering what happens when the level gets to zero in Ceiling Zero,

I suspect that the reason this doesn't work is because you MIGHT be using ProDOS to load the file into memory. There are too many differences between ProDOS and DOS 3.3. To use the integer basic loader file, you need to either have a dos 3.3 partition (don't know if it's possible on a sider) or you must stick with floppies to use your calendar program. I'm not aware of an Integer.Basic file usable under ProDOS. Integer BASIC has sort of went the way of DOS 3.2 (remember that) and the PC (ahem) Jr. I know a while back in A2-Central there was talk of (maybe) someone writing an integer basic system for ProDOS but I never heard any more about it. ProDOS uses the extra 16K for it's own ends and that's where Integer BASIC usually resides. If anyone knows about an Integer Basic usable under ProDOS I'd be interested in hearing about it.

Integer BASIC is unavailable under ProDOS since they both use the same
part of memory--the main bank-switched memory.

So why not store INTBASIC in an aux. bank of memory that ProDOS doesn't use, and conjure up some new code to handle the routing of files between INTBASIC and ProDOS, and possibly adding some phony DOS 3.3 routines to pass it through ProDOS. It would be simpler on a IIgs, but not impossible. I remember wishing it was possible to run INT ProDOS type files in ProDOS. Why have a filetype if you can't run the damn thing! This came about when I wanted to move all my games from multiple DOS 3.3 disks to a couple ProDOS 800K disks. Got to really hate people who would have their programs start at $07FD just so they could store a JMP there. A little special relocation code took care of that, although sometimes clobbering ProDOS, who cares. Once a game is loaded, going back to DOS isn't a normal thing that people would do. >----------------------------------------------------------------------------- >Scott Alfter _/_ > / v \ Apple II: >Internet: alfter@uns-helios.nevada.edu ( ( the power to be your best! > GEnie: S.ALFTER \_^_/ -- __ _____________ __ \ \_\ \__ __/ /_/ / The trigger has been pulled.
