On calc or computer or manually?

Wait, ASCII to tokens or tokens to ASCII?

 My issue was that I programmed in hex a lot, but I figured automating the process of computing labels would make my life easier  . Then I thought "What about other people using this?" And then I added commenting (still not reinstated), equate support, and text conversion.

I know I just took all of what I considered the most common equates and put it into one file and had the user define their own equates if they needed (and they could create their own). If you split it up into 5 files or whatever, will they be by some category?

Now, I'll just use this threat as a project thread.
Oh dear, there is no need to threaten  Freudian slip?

Yes, this was truly awesome getting to witness live amazingness while I also tried to create the same routine My attempt was extremely ugly compared to this  Beautiful code, Runer112

16-bit subtraction or a ;to make sure the c flag is reset. Not always necessary if you know the c flag will be reset
sbc hl,bc ;you can do sbc hl,de also.
32-bit addition (you mean two 32-bit inputs?) ;Inputs:
; HLBC is one of the 32-bit inputs
; DE points to the other 32-bit input in RAM
;Outputs:
; HLBC is the 32-bit result
; DE is incremented 3 times
; A=H
; c flag is set if there is an overflow
ld a,(de) \ inc de
add a,c \ ld c,a
ld a,(de) \ inc de
adc a,b \ ld b,a
ld a,(de) \ inc de
adc a,l \ ld l,a
ld a,(de)
adc a,h \ ld h,a
ret
Squaring and square rooting... I will think on it  Also, I am working on a mini math library that will include RAM based math (so all the values will be in RAM). It seems like a few of these commands will need to rely on some memory. If they do, I suggest using the OP registers (11 bytes of RAM each).

Cool, that looks like it will be useful, though I don't know anything computer-wise Also, your grammar and syntax are great What is your native language? Also, Welcome to Omnimaga!

Oh, the LD was just purely data. I used the inString( command to search the data for a match. So if you abuse this, you could make a compiler!

fwahahaha  I was showing off the fact that using this command, you can make a compiler in Grammer code

I think there is a reason why jacobly has an average of more than 1 uprate per 2 posts Good eye.

It is one of the Lovely Sequences  (I call them Lovely Sequences, I don't think anybody else does...) But yeah, Kerm seems to have made a decent job of accessing the Goto option without making the user go through the OS menu. Though, of course, that could be a hook, now that I think about it

That's okay, I have been looking at the code that is run when you actually press "Goto" and I am trying to see if there is a bcall that matches it. Maybe ask ThePenguin77 or KermM? I know DoorsCS has its own custom error routine and then lets you jump to the offending error.

So with two-byte multiplication, you can take advantage of the fact that add hl,hl is the same as shifting hl left. It even gives you the carry! So in this case:
ld hl,0
ld a,16
MultLoop:
add hl,hl ;shifts hl left
rl e \ rl d ;shifts de left and if hl overflowed, it overflows into de
jr nc,$+6 ;if the bit in DE is o, skip this chunk
add hl,bc ;add bc to hl (think of this as the first number)
jr nc,$+3 ;overflow into de
inc de
dec a
jr nz,MultLoop
ret
That will multiply DE times BC and return the result in DEHL. I will see if I can port a square root routine for 32-bit...
EDIT: changed inc e to inc de

Yes Typically you do rla, then check the next bit and if it is set, add the other register The rla at the beginning works because a starts at 0 so 0*0=0.
