Finding the position of a sub string within a strong

[Ray Parrish]

Hello,

I am starting to get a grasp on what can be done with regular 
expressions, and I now know how to extract a sub string from within 
another string if I know it's offset, and length.

The thing I haven't discovered during all of this reading is a way to 
return the position of a substring within another string.

How would I return the position of the sub string "zat" in the string 
"abczat1256"?

I know how to get the length of a string now, but not how to search 
within it yet. I have thought of a cludge which involves stripping 
character at a time from the front of the string into an array, but why 
re-invent the wheel when I'm sure there is already a simpler way to do this.

Thanks for any help you can be.

Later, Ray Parrish
