Trouble with Assembly

absoluteAquarian 15 May 2018 14:29

I am still learning assembly in the TI calculators (I use a TI-84+).
I came across the String Pixel Width program at the Assembly Hex Codes documentation here and it states:

This returns how wide a string is in pixels.

Here's the program for reference:

AsmPrgm
EFD74AD604C0
676FEB
4E234623EB
C5D5E51A
EFA342F5
EBEF9445
218D8477EFB44C06004F
F1E1D109C1
20020B13
0B1378B1
20DB
EF9247
EF5641
EFBF4A
C9

I compiled the assembly, which I named prgmZSTRLN, into prgmASMSTRLN.
The program runs fine, and I made sure to store the string in Ans.
I assumed that when the documentation stated that it returns a value, that I could implement it like any other method, e.g. randInt(row, column).

Example:

"Example
Example

Asm(prgmASMSTRLN)->A
Error

When I do this, I get a SYNTAX error. The returned value is not in Ans, even when I did the following:

"Example
Example

Asm(prgmASMSTRLN
Done

Ans
Example

What am I doing wrong?
What does the documentation mean when an assembly "returns" a value?
How do I access said value?
How do I store said value into a variable?

You do not need to compile hexcodes. Try running this code:

Asm(prgmZSTRLN
Ans

I got the same problem from before.

Ans still contained the string.

Make sure you have it typed correctly, Including the Enter for each new line. I just typed it into my calculator, and it works fine.

I found the problem.

I was missing this line at the end:

EF5641

It works now. Many thanks.
