Can anyone explain to me how to use the floating-point variables? I believe they are OP1-OP9 or something like that. I don't understand how they are stored to, how instructions are done with them, or how to output them on the screen. If anyone could fully explain them, that'd be great. TI-84PCE
Also, sometimes I see something like this:
Code:
What does $ mean?
Also, sometimes I see something like this:
Code:
jr nz,$+3What does $ mean?
$ stands for the current address in most (not all) (e)z80 assemblers. Notice that in this case the address is measured from the start of the jr instruction, so in this case it would jump forward by 1 byte after.
The OP variables are used to preform floating point math; yes. You can find more information about them by looking into the TI System Routine manual (Here). Also, Day 18 provides a lot of useful information for using them; better than I could do here
