Ahhh... Bsort = bubble sort (duh!). I glanced at the code for bsort
real fast, but I didn't look in depth. I thought it used the built in
IDL sort routine and then added some code to force it to keep stuff in
the proper order. I didn't realize it's a whole new implementation of
a bubble sort. Do you happen to know what type of sort the built in
idl sort routine implements?
