replaceText(tString, " +", TAB)

Note that is 2 characters : space and +

For example

> put replacetext("asd   qwe werer          z", " +", ",")

puts

> asd,qwe,werer,z

btw - Do you need to do anything special with a line like
[3 spaces] word1 [2 spaces] word2

The above replacetext will give
TAB word1 TAB word2 cr
which is probably what you want - but worth thinking about as a 
potential special case.
