ListExt 1.3   (details) 49/50 ENG   42KB/23KB
List extensions library forming a collection of list and string processing commands. Included are a variety of functions for analyzing, manipulating, and editing lists and strings. Most of the commands and functions in the library have been optimized for performance, and are much faster than standard RPL approaches with similar functionality. Includes commands to collate a list of sublists, count objects in a list, remove duplicates from a list, distribute list items into sublists, replace repeated elements with a single instance, replace list elements with a substitute object as indicated, roll the list, subdivide a list into sublists, create a list of integers, shuffle the contents of a list, and much more.

MultiStopwatch 1.0.0   (details) 49/50 ENG ESP DEU   422KB/19KB
ScreenshotMultiStopwatch is a library for the HP 49g+/50g (only) that provides standard stopwatch functions, but with the following additional features: 3 independent timers per data file, with a real-time console application to show them, console app manipulates timers at native Saturn speed (not ARM, but as accurate as is feasible with the clock on these systems), data is maintained between sessions, so the timers continue to run while performing other operations on the calculator. Can be run from ports 0-2. Most stopwatch functions have corresponding User RPL commands available. Supports printing to the HP 82240B (or compatible) printer.
