Barry: The subject of how to use .CO files comes up quite often. The story goes like this. A .CO file is a machine lnaguage file. The 8085 processor runs .CO files from with in a specific area in memory. When the .CO file is run, assuming you can see it on the menu, it is first copied to that "specific place in memory" then run. Thus, a running .CO file that is also in the menu, resides in your computer in two locations. But, in order for you to be able to run the .CO file, you must first reserve space in that special place in memory in which it will be copied and run. HOW TO RESERVE SPACE FOR A CO FILE 1) Go into BASIC and issue the following commands: CLEAR0,MAXRAM LOADM"filename.CO" Your computer will come back with three numbers coorisponding to the words: Top: End: Exe: CLEAR256,topnumber Substitute the actual number for the word "topnumber" 2) Exit BASIC back to the menu 3) Place your highlighter over the .CO file in your menu and hit <enter> That's it for now. There's more to the story but this should get you going. -Rick-
