HOW TO USE fig-FORTH 8080 CP/M 1. Boot CP/M (or CDOS). None of the disks supplied is bootable; you must use your own. 2. Insert the disk labeled "fig-FORTH 8080 CP/M v1.3" in drive A. A "DIR" will show: FORTH130.ASM the assembly source file FORTH130.COM above assembled for 32K bytes of memory and two 8" single density disk drives FORTH130.USE this explanation. If the your system is different from that described for the COM file, you can reassemble the ASM file using CP/M's assemblers ASM or MAC (not supplied). Enter "FORTH130" and a carriage return. After Forth is loaded and initialized, you should see: 8080 fig-FORTH 1.3 Remove this disk from drive A. Do not write on it using Forth because Forth does not use CP/M's directory or file structure. You can put other CP/M files on it using PIP (or XFER). 3. Insert an empty (but formatted) disk in drive A. This will become your "Forth screens disk." It will not be compatible with CP/M's file system; it should be used only by Forth. Use Forth's editor to put text onto this disk and LOAD to compile source programs. First, use the editor to put error messages on screens 4 and 5 (see the Installation Manual). Be sure to enter FLUSH after editing. All FORTH words must use upper case letters. Then say 1 WARNING ! to use the error messages. Try using . when the stack is empty; you should get the STACK EMPTY message. If you have a printer which works with CP/M, you can use it with this Forth by entering Control-P to turn it on or off. The first Control-P turns it on, the next turns it off, etc. See the fig Installation Manual for a Glossary listing the words available and for how to use the Editor. You can enter "VLIST" any time to see what words are usable. To terminate a VLIST before it is finished, enter any character.
