LSORT is highly efficient Saturn code that screams through a list and sorts it using Quicksort followed by an Insertion sort once the partition size reaches a certain point. I believe he's creating a hash for the individual elements and then basing the comparisons on the hash. It's a great example of the relative speed that can be obtained using Saturn code vs. SysRPL in this case. The entire list is sorted in less time than it takes a SysRPL loop to step through each list item making a simple comparison. As is his usual, Werner has done a fantastic job with LSORT.

LMAX/LMIN are just SysRPL wrappers that create an executable to pass to the internal STREAM command (which is itself another SysRPL program). The first version simply passed MAX or MIN, but the current version also does a pre-check for string arguments and passes a special subroutine for those.

Good thing I put them there, then.

Thanks!
