I don't get it

Post #7,942 by Fearless Freep 9/7/01 2:45:51 PM Reply	I don't get it It just loops through itself and anything that matches the block gets added to a temp collection to be returned and removed Do you mean how do you remove from within a loop? How do you change a collection while iterating over the collection? The loop internal to the method actually sets up an loop over the indices of the collection. The element to be removed used removed using it's index (#removeByIndex: ) #removeByIndex: just goes from the given index to end, scooting every element up one position and then cutting off the last element Jay O'Connor "Going places unmapped to do things unplanned to people unsuspecting"

Must go back and study Squeak some more. BTW, the message that you gave for VW doesn't seem to be standard in Squeak.

Sometimes makes for very very elegant code. Wade. "All around me are nothing but fakes Come with me on the biggest fake of all!"
