os

* Forwarded from BBRZXNet from : SAV/D.M.G./U.A. to: Raskazov Sergey Aleksandrovich subj : Approximate view of our microOS. date : 11-04-98 time: 17:43 Hello Sergey! I thought about this idea a little more and added a couple of thoughts. So: 1. What is it? This is a shell, not an OS based on Tr-DOS (like Windows itself). Disk with files of this the shell is no different from the usual one. The core contains 128 kB of RAM, i.e. unlike Is-DOS, this shell represents more resources (brains, access to I/O devises), in addition to this, a powerful device for accessing screen file and disk. It is quite possible that there will be Disk polling is not part of either Tr-DOS or MS-DOS. Access to the screen will be very sophisticated, i.e. everything procedures for displaying characters, printing sprites, windows, lines, points and in general all graphic objects that are basic (standard) will be filled into Bios. In the future we can see the creation of emulation multitasking, i.e. running multiple processes at the same time. This can be interpreted in two ways: a) everything works simultaneously, on three levels access: I. Prohibiting everything for the duration of its execution other processes (formatting, disk operations) II. Working in multitasking mode, i.e. onethe interrupt works one way, the other works differently, etc. and then everything repeats itself. (Most processes) III. One-time, called every interrupt (clock, music, key polling, etc.) b) All processes hang in memory, but only the process that is current, i.e. moving into another process you stop the previous one (but not destroy it) and start a new one. Moreover, when returning to the old process, you continue working in it from the moment where we graduated, and how as if you never left it. 2. What does this give? This shell will allow you to use quite effectively your resources (both computer and brain), because the ability to 'simultaneously' work in several processes will provide high speed and greater return. Next is the ease of downloading. Due to the fact that the core is TR-DOS, the shell loading speed will not be exceed the boot loading speed, so switching from shell to TrDos and back will take a minimum time. Simplicity and freedom of creativity. Obviously, the Bios will be configured to execute files : com, exe, bat (meaning analogies). Those. programs can be written in the form of a bat file, using bios resources and com swapping and exe files. In theory, this shell is based on the principle of convenienceobject-oriented programming, i.e. all this crap is aimed at solving a specific object-task, and so that this solution (writing program) was available to everyone. 3. For whom is this needed? Actually, this is intended to resuscitate life in Bobruisk. If every user is able write an executable file, then our connections will be filled not only with soap, but also with programs. 4. Alternative... Of course there is an alternative to this project - perhaps creating a design program using a tricky method: this a program is a piece of language, only more aimed towards specialization in user tasks. In my opinion, what I said above is not clear. So, let me explain: At the input there is a text file with the so-called. 'program' [actually call it a program under no circumstances]. The program compiles this file into an executable file. Now about the 'program': There are actually no operators in it - operators are the names of tasks launched together with the file, eg : Viewtxt Help.C, Call MAIN+.C, Load ANTI.C, Run boot.B. But these operators are not really operators, they are names tasks. But operators are also provided: Print, Cls, For etc. There are also functions: Inkey$, Len, Sqr, Sgn and etc. In theory, this is a highly specialized microlanguage, but inwhich only has a compiler. 5. Choice! In truth, all projects (Language, shell, designer) are very important and necessary. I want do everything, but, unfortunately, I have neither time nor physical capabilities to master so much grandiose projects. This raises the acute question of choosing the project which I'll be poking around this summer. Once I filled out my program of action, but since then so much has changed that we have to do it all over again transfer everything from the beginning. 6. Action program: 1. Add every little detail (CGA grafix editor & other) 2. Write a MODEM romp poker (ex-strip). 3. One of the super grandiose projects: Language - Shell - Designer - Interactive game - Step-by-step super strategy with self-developing intelligence (with the ability to support a modem option) A huge number of small programs, utilities, converters and etc. This is my grand plan for the near future! That's all for now, it's time to burn it to disk, otherwise... With the best wishes, SAV.
