Respected everyone suppose i provide the initial location of a node as $node_(0) set X_ 16.0 $node_(0) set Y_ 36.0
now if i want to assign the value of x position and y position of node 0 to another variable x1 and y1,how can i write that?? is it like this set x1 [expr $node_(0) set X_ 16.0] set y1 [expr $node_(0) set Y_ 36.0] but as soon as i try to run the program it shown an error "UNKNOWN VARIABLE set x1 "... how do i assign the coordinates to other variables? thank you Regards Suman
