Quick Routine
« on: October 01, 2011, 02:47:58 pm »
I need help. I am uncertain how to get input in z80. There's a program I'm looking to make, but can someone help me with this. I need to do this in assembly:

Code: [Select]
Disp "A:ROCKET MASS"
Prompt A
Disp "B:PREV RCKT VELOCITY"
Prompt B
Disp "PROPELLENT MASS"
Prompt C
Disp "D:PROPELLENT VELOCITY"
Prompt D
Disp "E:PLANET MASS"
Prompt E
Disp "F:END TIME"
Prompt F
Disp "G:INITIAL DISTANCE"
Prompt G

Sorry, I have never done anything like that, so I can't help off the top of my head :/ I know you can use the actual bcalls to those commands, I am just not sure of the syntax for things like prompt.

For getting the text, here's an awesome routine I made.

Code: [Select]

;output:
; b = length

;destroys:
; af, bc

.db "xsnida"

This routine allows you to type letters, but you can remove that ability.

Then, as far as making a number out of it. You could probably parse it yourself, and if you can't do that, you might be able to save it as a string and parse it into a TI float, though, I don't really know how to do that. (Probably undocumented.)

I would like to only be able to accept numbers as input.
I can handle the moving to Op.
Where does it save that to?

Oh, sorry, I mis-typed there.

This routine will get the numbers for you. It also allows you to type letters, but you can remove that ability*

To get rid of letters, just take out the alpha and 2nd functionality and make sure it always chooses a letter from NumTable:.


It saves the text wherever you want it to, just pass it HL. (It destroys 2 extra bytes after the maximum length you specify for the string)

Ok, so let me just double check. To make it only accept numbers, remove the upper and lowercase data tables, and take out the 2nd and Alpha key checks?

Rather than give you some long and complicated response, here is the code for numbers only:

I didn't test it, so it might give you a assembler error somewhere. Also, I left in the little E and the negative sign in case you want to handle them. If you don't, you can just zero them out in the character list.
