Hex Opcodes

[kinkoa]

These are pretty neat if you need help programming on a cumputer i would suggest you start with learning something easy like C# or Java both i found to be fairly simple to use when i started programming, but the hardest thing to program in is binary, because computers are so complex they need something that can handle this, most computers use 64-bit binary which is just:

It would really be nice to learn how to program on a computer... and I would love to learn how to program my computer in hex... The problem is, my computer skills are on the horrible side, so I do not even know how to get to a programming environment !_!

Program a PC in hex? Maybe in 1985, but not now. The days when a single person could know everything there is to know about a computer have long past. If you really want an idea what goes into a modern OS, take a look at MenuetOS , an OS programmed entirely in assembly . Programming in hex for Windows would not be fun: the PE format specification is nearly 100 pages long, and you have to deal with relocations.

On a less discouraging note, Microsoft's Simple Basic might provide a means for you to get started with PC programming without too much hassle. Simple BASIC is designed as a sort of starter language, for you to get used to programming. From there, I would probably move on to C#.

Yeah, I kinda figured, but it would still be cool. I am sure if I wanted to I could pick up some stuff, though because generally opcodes follow a pattern. I am sure I won't be able to program a 64-bit computer in straight hex, a 32-bit maybe, and a 16-bit definitely and an 8-bit processor definitely.

Can you make an On Break oppcode? I've been looking all over to find one for my BASIC passcode calculator security program. (It already runs automatically with the Startup app.)

[Xeda112358]

Do you mean something to cause a "ERR:BREAK"? If you want that, you can do FDCB09E6C9 should cause the error. If you want to block it, you will want to download ONBlock because I have never learned how to use interrupts (sorry).

[DrDnar]

Interrupts, properly implemented, are simple and easy to use. TI didn't implement them properly. I guess, as far as they're concerned, there was no need to implement IM 2 correctly, or at least useably.

Does anyone know of a Hexcode that will allow me to add greek letters to my programs? I've played around with the char program and can get just the letters I need to display to display with it but getting them to display where I want them to be (In a physics formula) is beyound my ability.

[Xeda112358]

Hmm, I made this program if you want to give it a try
http://www.ticalc.org/archives/files/fileinfo/425/42505.html
It includes the opcode and the readme tells you how to use it to get a string of all the interesting chars such as greek letters. You can then use them in a string to display them wherever you need them The nice thing is that if you know the value for the char, you can pass it to prgmXTRA and it will spit out the number as a string. You can also use a program called DataString to do similar things.

I hope that helps! If you need more info, feel free to ask

I don't have a link cable. I tried typing the hexcode from the zip file into an asmprog and runnign it but it did not work. I twould have been great if I could have stored Greek letters into a str vars though.

[Xeda112358]

Okay, that is odd... maybe the opcode was input wrong? .__. I tried it to make sure and it worked. Here is a screenie of what I did:

The result was all the letters stored as a string to Str1 (and Ans)

EDIT: Also, after looking at that source (which I made a looong time ago), I see that I need to update it. I can make it smaller, now >.>

[erik.wiggins]

I got it to work thanks a bunch. Now I can just play around with it and get only the letter I need in the string and then create a short sub prg to get only the letter I need out of the string. Once again thanks.

[Xeda112358]

No problem! I am glad it worked Also, might I ask what the program is that you are making? Physics wasn't my strong point, but the formulas where always fun XD

[erik.wiggins]

Just a formula sheet to start with. Now that I can use the Greek letters I can put in those nice formulas like Φ=Q/ϵ Of course the real hand part is τ since t=time and T= tension. So far I've made a custom menu that parses str1 for menu entries and returns the menu item selected as a number in S. The next thing to do is to build all of my formulas using the nice little program you provided me with and then eventually I'll have the program solve the equations for me. But that is a long way down the road. I've got 2 semesters of College Physics formulas to plug in first.

Oh dear, well good luck!
