[RESOLVED] Replace All Duplicates in String

[agmorgan]

I have a method that builds up a comma separated list returned as a string.
Unfortunately it sometimes returns stuff like

Tom,,,,,,Dick,,,,,,Harry

I tried replace to return single commas e.g

Replace (strNames, ",,", ",")

but it only replaces some of them. e.g.

Tom,,,Dick,,,Harry

Is there a recursive ReplaceAll function or do I have to write my own?
