Registers and such

[Amos Vryhof]

Well, with all of the info I learned in the other topic, I got a
good document on x86 registers, indexes, pointers and such.

I will need to know more, so please bear with me...I am new to
playing with this stuff.

If you don't feel like answering these questions, feel free to
ignore me, or point me to a good reference.

(I plan to get my DOS programming books back soon)

How do I retreive ASCIIZ strings?

ie: DS:SI -> 64-byte buffer for ASCIZ pathname

You read them byte by byte, starting at the address specified, in say DS:SI, and continue reading until you encounter a CHR$(0).

Or are you looking for ASM/BASIC code to do this? If so, then using BASIC code is probably the easiest, unless you just want a pure ASM equivalent:

DIM x AS ASCIIZ PTR
x = VARPTR32(var) ' or assign the address of asciiz string data
PRINT @x

That should be enough information to keep me busy for awhile...

Thanks Lance
