Splitting a string

[zskater]

when setting the variable testVar to the following expression

set testVar [eval .c coords $Move(utag)]


It returns a string containing the co ordinates of the rectangle that has been selected
on the canvas. eg. 80.0 140.0 160.0 260.0
How would i then split that variable up into the four seperate co-ordinate variables
x1 y1 x2 y2

Cheers
Steve

foreach {x1 y1 x2 y2} $testVar {}
