I need to parse a string like:

732:1:29:18457:3

Into an array of variables:
DIM ntach(513) AS LONG

So ntach(1) would contain 732
ntach(2) would contain 1
ntach(3) would contain 29
ntach(4) would contain 18457 and
ntach(5) would contain 3

Each string can contain between 1 and 513 multi-digit numbers.
Each number can have between 1 and 6 digits.

If I was in a worksheet and if there were less than 256 numbers per string,
I would use Text to Columns€¦

What should I do in VBA?
