[Tutor] word wrapping a string

[Lance]

Hi All,

I would like to write text that word wraps to two or three levels of tab
stops.

For example....

y = 30*'hello world'
s = 'start\t' + y

This won't do it... since the string will continue off the screen.

Is there a module or can anyone suggest how I might write a procedure to
wrap y at the tab stop, irrespective of the length of y?

I want the result to look like this:

start     hello world hello world.....
           world hello world....

Thanks in advance,
Lance
