Field length manipulation question?

[DiscoPants]

Hello, I wonder if anybody can help. I have a large awk program which outputs a list of characters with any number of null spaces between them follwed by a varying number of null spaces., I need to format the output so as to just show the field without the trailing spaces.

For example, I may have:-
'Ab cde fghijk l mnop qr s '

And need to print
'Ab cde fghijk l mnop qr s'

Is there a simple way of doing this, At the moment I can only thing of reading into an array and counting back til I hit the last character

Cheers

return str;
