split string

Hi;

I have a string "1234200202020020590010001020",
How to split it into ...
1234 20020202002059 001 0001 020
and assign into different variable according to the length.

If the string is "1234,20020202002059,001,0001,020",
How to split it into ...
1234 20020202002059 001 0001 020
and assign into different variable in a loop.


Cheers;
