Talk:Basic Input/Output Commands

I would just appreciate an opinion on this new low-level esoteric programming language I made up... --202.156.14.10 08:00, 29 February 2012 (UTC)

How do you do conditionals and loops? —ehird 15:41, 29 February 2012 (UTC)

It's probably esoteric... because you can't do conditional code, loops, or functions --202.156.14.10 13:57, 2 March 2012 (UTC)

Well, unusable for programming isn't the same thing as esoteric :) But it seems you've added conditionals and some jumps, so it looks like a loop should be possible. (By the way, there's no need to archive the page when there's only one short discussion (which isn't even over yet) — but when there is, the {{archive}} template simplifies things.) —ehird 07:41, 5 March 2012 (UTC)

The point of Basic Input/Output Commander?

The point of Basic Input/Output Commander that I thought up is to be an almost-esoteric low-level programming language which is meant for writing esoteric programming language interpreters. If you try a thousand times to write a working interpreter using this programming language and you sill find it impossible to, then try to improve this programming language until you can write a working interpreter using it but don't try to destroy the almost-esoteric nature of it. It also shows how everything in computers are numbers.

Possible FAQs

• How did you convert text to character numbers?

This is an advanced algorithm, but you can find an easy converter here (Convert ASCII text into Decimal/Unicode, not Padded, use "" as a delimeter left and " " as a delimeter right)

• How do you process a full line of code at a time?

An example clone of the Brainfuck interpreter, but which interprets a line of code instead of a symbol at once (but with one bug: pointer always gets reset to 0 after a line of code is run), is shown below:

// check if brainfuck program tries to use virtual memory below 0

• What about commands of more than one character?

Nobody knows yet. Figure it out yourself, but you may need to use lots of sets of switches in memory to check through lots of characters as probably one command.

External devices?

Since this is based purely on I/O, could you not use external devices (say a 4017 or something) for logic operations? Or is that against the point of the language? --(this comment by 130.160.145.214 at 23:32, 10 December 2012‎ UTC; please sign your comments with ~~~~)
