Is anyone familiar with any type of program which is similar to the IBM's Double DOS? For those of you who don't know what Double DOS is, it was a program loaded into ram which allowed you to split the CPU (you could flip between two different programs). I know about that old program for the Apple called Double DOS which let you put DOS and ProDOS on a single 5.25" disk. Chris chris@msus1.bitnet

For those of you who don't know what Double DOS is, it was a not quite, but I did once write a program to split the Apple II ram into 2 sections to allow switching between 2 basic programs. It was amazingly easy since I had documentation of Applesofts allocations. I think it took about 8 hours to write. Frank Filz

Do you mean switching like SoftSwitch (for the GS)? Or are you refering to true multitasking, where the cpu does the switching? > Chris Phil prl3546@tahoma.UUCP

Softswitch works, it allows you to switch between up to 9 different 8 bit applications. It does not allow you to run multiple 16 bit applications. It works only on the IIGS and allows you to switch any program that lets you get to the classic desk accessories. This includes many copy protected games. It allows you to snatch graphic images from any program you are running and also allows you to save and later reload the memory image of any switchable 8 Bit program. I don't use it very often, but it has come in handy more than once. Seymour

Is this a copywrited, shareware, or freeware program...I guess what I'm
getting to is, where can I find it?
Also, does it allow a program to continue running while you switch to another
application? I'm thinking that it would be pretty nice to set up a down or up
load, and be able to flip to another job.

Unfortunatly, it won't work that way and you do need a mac and multi-finder to run two or more programs at the same time. I understand it could be done on a IIgs but I'm darned if I could write it. _______________________________________________________________________________ |UUCP: [ucsd, nosc] ..!crash!pro-europa!paul | Texas SysOps Unite! | |INET: paul@pro-europa.cts.com | Join COSUARD!

Extra K makes your IIc or IIe look like two 64K Apples. >Softswitch makes your IIgs look like numerous Apples. It should be noted that extra K will run on a IIe, IIc, or Laser 128 also. I've been meaning to look into getting Daemon to actually run two seperate programs at the same time, one in each half of memory. It wouldn't be too different than running background tasks. Has anyone ever written one of these programs that runs a program in the other bank and switches? I figure those of us with 2.0 Megahertz or faster speed should still have acceptable speed. Also I did some more work on Daemon and the Window routines over the summer, but have been too busy lately to upload them. The window routines still have a bug or two I haven't killed, but as my parents keep reminding me, I'm at college to pass courses, not write software. Anywho, I should have somethin up in the next week, but don't hold me to it. --- Michael J Pender Jr Box 1942 c/o W.P.I.
