Request for hex ASM code

[Iambian]

I just need a collection of short snippets of hex ASM code that might prove useful to the BASIC programmer. You know, simple stuff like inverting hex, speeding up your calculator, killing the Done, removing the run indicator, etc.

This information will be included in a section of the readme that will support the included "exechex" command. You need not include the final "C9" if there is one, as the application automatically appends that to the code. Also, try not to make the code any longer than 767 bytes (1534 characters).

Thanks.

I love Celtic3 , but I have a few suggestions for additions. I made a program called QSprite (it is on TICalc) and it can take an 8x8 portion of the screen and convert it to a tokenized, 8 byte string. It also has a function that is like the Identity(5 thing, except with a tokenized string. Feel free to use any parts of the source (it may be a rather unconventional way of writing a source, but I do on-calc programming). I will attach the source. If you want a list of all the calls and their addresses, they can be found on TI-Calc, too.

By the way, Celtic3 was the push that helped me become an assembly programmer, so thanks.

Sorry, I just realised that. These should be better; It is part of my EnLib program:

20-Multi-level Battery Check
This returns a number from 0 to 4 for the battery level.
0 is the worst and 4 is the best. The value is stored to Ans.

31-Graph→Screen
This neat routine will put the graph screen image on the
home screen.

32-Screen→Graph
This will put the home screen image on the graph screen.

Each of the commands in EnLib has its opcode included. Except for Xtra X, they all work on there own. The last one will need an address modified.

I'm pretty sure to run it without Celtic you need to add c9 to the end

[ztrumpet]

Right. I don't want it to keep going, and get a RAM clear.
I think. :biggrin:

Yes, that is all true. Thanks for reminding me about the battery check thing. I knew I was forgetting something. The whole "C9" thing is explained in the EnLib file. The file will be included with this post if you want all of them. Most are the regular ones I found as a BASIC programmer and some I have made as an assembly programmer. With the last opcode, I don't know if Celtic3 runs the program from appBackUpScreen or saveSScreen, so do not use that one. If you only want to use the ExecHex function, check out ASMCall.

[Iambian]

Hex ASM programs that run using Celtic III are executed from the SaveSScreen buffer. The appbackupscreen buffer is used internally by Celtic III for variables that include how to properly exit the application, so that buffer shouldn't be messed with.

If you absolutely must use the appbackupscreen, be sure to preserve the two bytes at appbackupscreen+37 ($9897) and load them back when you're done with the routine. They hold the address to "return" to. If you choose to use the value to do the return yourself instead of having Celtic III perform the job for you, do the following:
