Bernard, I have been able to figure out how to load, save, and edit (mostly) alphabets, data, and grammars. The interface is fairly intuitive and vaguely familiar after having used BP2. I like the "smart cursor" feature that skips over each bol/token with a single press of the arrow key! :) I have tried to derive something from a grammar but I am probably not understanding the correct way to do so. I'm also not sure what the lexical requirements are for variables and terminals. I created an alphabet with the symbols C4, D4, E4 ... C5, D5 and started creating a grammar with them, then it occurred to me that BP1 might think they are variables since it has no notion of simple notes (right?). So, I added q,w,e,r,t,y to my alphabet and finished my grammar like this: S --> C4 D4 E4 C4 --> q C4 r D4 --> w e D4 --> e w E4 --> t y E4 --> y t C4 --> D4 C4 --> E4 (I included spaces after each token in the alphabet. I don't know if that is valid but it does display the way I wanted it to in the Data & Grammar editors). When I select "Compute" from the Grammar menu, I am taken to the first data item and asked if I want to "Revise processing?". I don't know what that means. I reply "Y" to that and "Step by Step?" and then BP1 beeps and displays the item (unchanged) along with the menu "Q)uit P)rint R)epeat K)eep ..." Sometimes I get a different sequence of prompts for "Compute" including "First grammar?" and "Last grammar?" followed by the menu "A)nalyse S)ynthesize D)estroy structure ..." I reply with 1, 1, and S for Synthesize, "N" to "Create templates?" and "Systematic tree-search?", "Y" to "Step by Step?" and I'm back at the menu "Q)uit P)rint R)epeat K)eep ..." with no change or derivation of the item. (I performed these steps starting from the Data menu for an item containing only "S"). *shrug* There is no need for you to try to explain right now what is happening and where I am going wrong. As you said in your message, you "have not yet found the way of producing items!" either. ;-) I can wait until you have time to consult with Jim Kippen and/or to work it out on your own. I'm curious to hear what the "Sound" option does but I think you may be right that Catakig may not be fully functional in that area. I hear nothing when I choose that option from the menu. (But I also have no idea what sort of data is required for it to work). Well, BP1 is lots of fun. It's tempting to keep playing with it instead of working on other things. ;-) But there are issues to address in email and the BP3 code. Anthony P.S. I also had to read the Catakig User Guide just to figure out how to turn the Apple II on. Not very intuitive. :( On 8/19/20, 1:08 AM, Bernard Bel wrote: > This is very encouraging! > > Next week I will post a tutorial on http://bolprocessor.org to explain > how to install an emulator and start running BP1.
