[DQSD-Devel] New Function: randomsearch

[Neel Doshi]

Hello again,

Below is a function called randomsearch.  Randomsearch takes two
parameters.  The first is the name of a QuickSearch function.  The
second is a path/name of a txt file.  The function will pull a random
line out of the text file and apply the given function to it.  I use
this function to implement a word-of-the-day study tool, but I can
imagine a number of other educational purposes.

Would one of you administrators mind adding this to the source if the
group deems it worthy?  I apologize for no longer having any CVS tools
set up.  Let me know if you wish me to send this in as an attachment.

Thanks,

Neel
