Free42 v1.4.64

News via http://www.aep-emu.de/

Free42 is a complete re-implementation of the HP-42S scientific programmable RPN calculator,was made from 1988 until 1995 by Hewlett-Packard and the HP-82240 printer. Free42 was written from scratch, without using any HP code. You do not need any ROM images in order to use it, yet it is fully HP-42S compatible.

Free42 HISTORY

30-03-2010: release 1.4.64

* Implemented some more Time Module functions: DATE+, DDAYS, and DOW.

28-03-2010: release 1.4.63

* iPhone version: implemented ACCEL, LOCAT, and HEADING functions, for querying
the device´s accelerometer, location services (GPS on the 3G and 3GS; WiFi-
based on all other models), and compass (3GS only).
* All versions except Mac Dashboard: for skins, increased the maximum macro
length from 31 to 63. The old limit was too small to allow macros that step
forward all the way to the end of the FCN catalog, and supporting such macros
is necessary now that the length of the FCN catalog is no longer fixed at 42
rows.
* Also, changed several macros in the HP-41 and HP42CY skins where the FCN
catalog was being traversed backwards, replacing N repetitions of "up" with
42-N repetitions of "down", so they will work correctly in the presence of an
extended FCN catalog. (None of the other skins currently in the Free42
repository traverse the FCN catalog backwards, so they don´t need updating.)
* PalmOS version: turning off printing did not flush the GIF file, so you´d end
up with a truncated image. Fixed.
* When COMPLEX is executed with a complex number or complex matrix in X, and
POLAR mode is active, it is possible for range errors to occur. Free42 would
simply substitute POS_HUGE_VAL in such cases, but that was incorrect; it
should report Out of Range or substitute POS_HUGE_VAL depending on the
setting of flag 24. Fixed.
* R/S can now be pressed using the PC keyboard even when ALPHA mode is active.
