Re: FLASH: set variable randomly, numbers should only be taken once

[Helen Triolo]

Hats off to you once again, Branden, for an efficient (and clever) way

to solve exactly the problem that was given.  I stuck it in the database

(of course) and added a modification for doing the same to an ordinary

"array" (eg, var1-var5) too.


Regards,

Helen
