I have been working on implementing two new string operators for comet 2007 and comet 2008. They are:

if a$ soundslike b$ .....
and
if a$ contains b$ ....

Soundslike uses the soundex algorithm as specified in Knuth vol 3. I have attached an IBS program to this post that demonstrates this function. Basically Soundslike makes 2 soundex digests and compares them. If the digests are identical, soundslike results is a true condition.

Contains is basically like a case insensitive pos function it results in a true state if the first string contains the second. It is NOT case sensitive though.

I realize that these 2 string operators could be coded in IBS, but it is SO much more convenient to just make them part of an expression.

They will be available in the 389 release.
