[REBOL] Re: count function
From: jelinem1:nationwide at: 5-Jul-2001 9:33
I liked Anton's solution for 'count so well that I copied it and searched
for agood place to put it into my shell.r - only to find that I already
had a function to do this. Not as efficient (I've timed them for the case
of searching strings) but takes a different approach:
occur: function [
"Count the number of times the given value occurs in the given
series"
some-series [series!]
some-value
][c][
c: 0
parse/all some-series [any [thru some-value (c: 1 + c)]]
c
]

Here's another way:
count: func [s t /local n][
n: 0
while [s: find/tail s t][n: n + 1]
]
