Nah, native gambas datatypes don't have methods (except the array 
classes in the gb core component.) But here's an equivalent one 
liner in gambas:

newString = join(' ', reverse(split(' ', myString)))

assuming one writes reverse() as (warning, pseudo code ahead):

function reverse(instring as String[]) as String[]
	dim outstring as String[]
	dim i as integer
	for i = 1 to instring.count
		outstring.add(instring[instring.count - i]) 
		' remember, arrays go from 0 to array.count - 1
	next
	return outstring
end

Of course a reverse() that just reverses a string is just as 
trivial to write, quite seldom used, and therefore I don't 
understand what this whole thread is about ;)

And don't the gambas gb component's array types have push and pop 
methods, speaking of lists
