Re: What is up with the 'FIND' function?

You are confusing find() and match()...
find() searches a sequence looking for an element...
constant haystack1 = { {1}, {2}, {3}, {4}, {5}, {6} }
constant haystack2 = { 1, 2, 3, 4, 5, 6 }
constant needle1 = {3}
constant needle2 = 3

? find( needle1, haystack1 ) --finds {3} within haystack1, prints 3
? match( needle2, haystack2 ) --finds a slice of haystack2 matching
needle2, prints 3

all other combinations will return 0.
