Replaces the header with one that shows more information, including a memory graph, implements a condensed-path display, replaces the variable softmenu with a Meta Kernel-style one, shows errors in status area and more.
Messages can only partly be handled at the user level in the ERROR menu. This situation improves considerably with Msgman. All built-in messages can conveniently be called to the stack, and you can find all built-in messages containing a given text fragment. Using its number instead of a message itself saves bytes in your programs and makes the message even language-sensitive. Msgman has one page only. The first 3 commands deal with built-in messages, the last 3 with message display, preferably in the new header of the HP 49g+. You can flash a message in the new header, or display it in two lines in the header, similar to PROMPT but without suspending with HALT. And you can insert a small text into the header at a suitable place.
When given any convertible unit, MUC will return a full screen selection of all possible conversions to choose from.

This is a a browser program written completely in User RPL. It will take a list of data from the first level of the stack and all your data will be displayed on the graphic environment called in User RPL (PICT). A bar will be shown and with up and down arrow keys you can "navigate" through your data or results. Optimized for the 50g.
Stacker4x compresses and decompresses on the fly all data handled by the user, so that the user can enjoy the benefits of compression without thinking about it. Everything is fully automated and once the library is installed, it will activate itself and intercept calls to STO and RCL.

Allows setting setting date and time in a nice graphic environement with a running analog clock and a (month) calendar. The clock hands are moved with some keys as if you would move them on a real clock with your finger tips. Powerful calibration tools for the HP 49 clock are included as well. One can virtually browse through the calendar, in steps of a day, a week, a month or a year, even through the centuries. Thus, you see how the month calendar looks ten years from now, say, and make your plans. You can also easily set date and time after a battery collaps etc. There is also a world map with a moving noon meridian. Hence, so you'll know where it is noon at present. You can also set the 24 time-zone and in this way readily determine the local time of big towns in the whole world.

Extended Time, Date, Calendar and Astronomical routines for the HP 48G(X) and 49G(+). Part of these routines are ported from the invaluable HP-41C CALENDARS Users' Library Solutions. The astronomical routines include calculation of times of sunrise, transit and sunset, moon phases, and seasons.
Calendar time and astronomical routines for the HP 49G(+). Part of these routines are ported from the invaluable HP-41C CALENDARS Users' Library Solutions. The astronomical routines include calculation of times of sunrise, transit and sunset, moon phases, and seasons. Version 2 is more user friendly than version 1.1 in that INFORM and INPUT forms and a CHOOSE box have been written for the most important conversions. In version 2.1 user input is further improved. The separate subroutines have been maintained for those who want to use them for their own calculations.

World time clock for the 49G/g+.
Starts your calculator in RPN mode, with a selection of the author's favorite key assignments, mostly written in System RPL directly in Debug4x.
