- Running the 4xFORTH DEMO System
-
-
- Files Required
- --------------
- The following files are necessary to run 4xFORTH:
-
- FORTH.PRG The loader for the FORTH image.
-
- FORTH.DAT The binary image of 4xFORTH
-
- FORTH.BLK The blocks making up the system
- loaded after startup. (This file
- actually contains considerable
- free space.)
-
- Startup Sequence
- ----------------
- 4xFORTH startup should be done in the following sequence:
-
- 1. Select MEDIUM resolution from the SET PREFERENCES
- menu. The demo is set up to run on a color tube
- under medium resolution.
-
- 2. Install the program FORTH.PRG as a TOS
- program. If you don't do this, 4xFORTH
- will run, but the cursor will NOT appear
- when you exit from the initial demo.
-
- 3. "DOUBLE CLICK" the FORTH.PRG icon.
-
- 4. FORTH.PRG will load the FORTH.DAT image of
- 4xFORTH and start it. Upon startup 4xFORTH
- will complete the DEMO system by loading
- some of the blocks in the FORTH.BLK file.
-
- When 4xFORTH has completed the load of the DEMO code, it will
- create a 64 block ram disk and move some blocks necessary to run
- the demo to the ram disk. The system will then make the ram disk
- the system device, and start the demo.
-
-
-
- Exiting to TOS
- --------------
- Execution of the following command will cause the 4xFORTH system
- to terminate execution, and a return to the operating system (TOS).
-
- BYE <cr>
-
-
- Available Memory
- ----------------
-
- The amount of memory available to 4xFORTH after startup is
- dependent upon the number of desk accessories loaded by the
- operating system at start up. Using the 5/29/85 version of
- TOS, the available memory with all desk accessories loaded
- will be about 164kb. If you rename the <name>.ACC files
- on the boot disk to <name>.ACS (or any other extension),
- they will not be loaded upon reboot. This can result in
- about 30 kb of additional space being made available to
- the 4xFORTH user.
-
-
- What You Can and Can't Do
- -------------------------
- The demo allows you to do and use all of the functions of 4xFORTH
- except the accessing of the Atari file system, and the saving of
- ram disk to a physical disk drive. The demo system has NO file
- oriented mass storage read/write driver after start up. Be warned
- that blocks you build containing programs will be lost when you exit
- to TOS.
