TI-BASIC to Asm Comparisons

z80 » Beginner

I had lost all copies of this page for a while and thanks to Andreas Finne who happened to have a copy backed up, the chart is back up.

Most TI86 owners are already proficient in TI-BASIC. To make use of that knowledge, I've constructed a table with common TI-BASIC operations and what it would look like in z80 assembler. All used assembler instructions are documented in the Instructions Section.

:a+1→a
		

inc a

	

:a+45→a
		

add a,45

	

:ClLCD
		

call _clrLCD

	

:a→b
		

ld b,a

	

:If a==23
:Goto aIs23
		

cp 23
jr z,aIs23

	

:If a==23
:Then
:Ais23
:End

cp 23
call z,Ais23

	

:For(b,1,10)
:ClLCD
:a+1→a
:End
		

	ld b,10
for_loop:
	call _clrLCD
	inc a
	djnz for_loop

	

:ClLCD
:Disp "Shutup"
		

	call _clrLCD
	call _homeup
	ld hl,string_label
	jp _puts
string_label: .db "Shutup",0
