Alright, I've been trying forever to do these commands and need
serious help.Please tell me what I'm doing wrong...

Turning off the power:When I use these commands, my calc crashes when it turns back on...

DI
LD A,001h
OUT (003),A
LD A,000h
OUT (004),A
EX AF,AF'
EXX
EI

Storing to ans:I can't get my value to store to OP1...

LD HL,25
LD DE,OP1
LDIR
BCALL STOANS

Creating Programs:This always crashes...

LD HL,prgmname
LD DE,OP1
LD BC,5
LDIR
BCALL CHKFINDSYM
BCALL CREATEPROG
RET
prgmname:
.db PROGOBJ,"PRGM",0

It would be nice also if anyone who uses ONCALC COMPILER BETA 8 could tell me how to use these on it too.

Here's how I usually do it:

Code:


Try this instead:
Code:

TANK OO TANK OO TANK OO...

However I still rest with the problem that I can't store to Op1 on the Oncalc compiler beta 8...Any suggestions?

Most of my work is done on the go and it would help alot when most all ASM commands are op1 based.

when I store values to op1 I use code like this...

LD HL,5
LD DE,Op1
LDIR

Last time I tried this my calc crashed so bad my OS was erased and everything on my calc disapeared

you forgot to set bc to how many bytes to move
and what you wanted to move probably wasn't at $0005, which is where you told it.

Code:

it puts what is at address in OP1

You've inadvertently revealed the problem that xenonparadox is running into: Op1 can only hold **9 bytes**. You have to put your Ans string into something (hint: how about a temporary String variable?) and then point Op1 at that.

I always assumed ans was stored in OP format.

Nope. Note that little mov9toop1?

The OPn variables are 11 bytes each, not nine, for what it's worth.

but 2 of them are only used to get more precision when doing FP math

Sorry, yeah, that. Of course, they have to be to hold the 11 bytes of a real during use as temp reals for calculation.

I think the problem is using CREATEPROG the wrong way.

Oh yeah, that too. I just assumed he was not failing at something that obvious.

All three look like he wasn't really sure what the commands did when he wrote it. for example, the swap with the shadow registers in the first one. Why did you do that, xenon?

Actually, that's kinda logical in this circumstance, since we're dealing with something interrupt-based (although completely wrong); I agree that the other ones are more trying to do BASIC-style cobbling of commands without understanding how the glue between them works.

I used to write code like that, but I can't remember when or how I learned to write working z80.

I want to learn Z80 or ASM. Are there any good OnCalc assemblers, because I'm not an admin on my own laptop.

You don't have to be an admin to run assemblers like Brass or TASM. I usually use Brass and DevPac8x; my favorite tutorial is z80 ASM in 28 Days.

But u need to be an admin to install them.

No, they're both just executables. You just download them and run them to assemble stuff.

I blame my ignorance of the CREATPROG function on the creator of ASM Guru.About 96% of all his examples have crashed my calc.

So I was wondering, when calc84 made Beta Compiler 8, why didn't he combine the ZCOMPILE prgms into one asm prgm?

Or maybe capitalize all commands with the exception of the .db command?With only four ways to write .db (.db .DB .Db .dB) it takes little extra space and would allow lowercase characters.

Just as a quick add-in how do you use the DoorsCS library commands in Beta Compiler?This doesn't work...


Code:


I know this ones gonna give me more criticism than Britney Spear's haircut in 2000...

Just so no one thinks Kerm's paranoid, calc84 used to be Kerm... sorry...

Can someone tell me if there is a better compiler than Beta Compiler 8?
