Is there a function to generate random numbers?

Hi,
I am one of the fond users of AutoCAD and Visual Lisp. I am developing an animation software in AutoCAD using Vlisp, for which a function that could generate random numbers or that could return a random number would be handy.

Currently I manage by running an external C-application to generate a list of ran. nos. and save as a text file. The operation by this way is not smooth. So, if anyone knows any other way of generating a random number thru Vlisp would be helpful to me.

thanks,
Yuvaraj.

You could ...

.... use Kenny Ramage's code: http://www.afralisp.com/tips2.htm

.... use DOSLIB: http://www.mcneel.com/cgi-bin/download.cgi?doslib.

.... use a vba call (randomize and rnd).

.... write and compile your own activex dll with related functionality.

.... use c++/objectarx for the app itself and then use srand from the stdlib.

.... exploit other internet resources http://tinyurl.com/2znyh

<imho>None of my business, but "animation software" using lisp? At face
value I'd consider another development platform better suited (perhaps
c++) lest you continually encounter language roadblocks</imho>
