How to split a long text.

Hi,

I have a long text like (0001001352, 0001001683, 0001001457, 0001236530, ............... continues). I don’t how long will be the string length either it may contain 1 or more than one numbers.

So my requirement is to split at each comma and store in a range.

If I use split then I don't know how many local fields I need to be declare to hold those split values.

I want to know is their any function module or class, which splits the string at comma and stores in internal table? So that I can store those into my range table.

Regards,

Kumar
