using a lisp memory address

[Phil]

Is there a way to take the raw address of memory of a simple text variable.

like something equivalent to this pseudo code:

(setq st "test string")
(addressof st)

I am writing a small win98 asm utility program to copy text to the clipboard since lisp has no such facility.

Why not just use (dos_clipboard <string>) from DOSLib,

thx, didn't know about it but I see it is arx file.
I am running toolkit lisp enabler with autocad LT
and it doesn't accept arx file.

I already wrote a small 3k assembly program to use with lisp winapp command, but it will be limited to the command-line arg limit of 128bytes.

This suits me fine but if I could access mem location
of any string length, I could modify my program to accept the larger strings if needed in future.

Since this is the customization group., it sounds like Phil is trying to write his own routine, not rely on a third party app.

I know full well what this group is. I've been here for over 5 years. Many people use DOSLib to extend the abilities of LISP and I suggested it because I didn't know if Phil knew about it's functionality. As it turns out he's using LT so he can't use the ARX without a 3rd party add-on.

I'm suer if Phil was using that 3rd party add-on or the "full" version of AutoCAD he'd use that instead of his little Assembly program.

DOSLib is 100% geared towards customization. I know of NO end users, who don't do customization that, use it for getting their work done.

I see you don't have any suggestions on how to access a memory address through AutoLISP. Why did you reply?
