The firmware for previous REX models was written by Starfish Software, but the REX 6000, though modeled on previous versions, included a complete re-write of the firmware. The REX 6000 does not support handwriting recognition and to enter data, a virtual keyboard is used. The standard REX 6000 has an American keyboard layout, although third ...
The line-oriented debugger DEBUG.EXE is an external command in operating systems such as DOS, OS/2 and Windows (only in 16-bit/32-bit versions [1]).. DEBUG can act as an assembler, disassembler, or hex dump program allowing users to interactively examine memory contents (in assembly language, hexadecimal or ASCII), make changes, and selectively execute COM, EXE and other file types.
It is the primary scripting language in some operating systems including OS/2, MVS, VM, AmigaOS and is used for macros in some software including SPF/PC, KEDIT, THE and ZOC. With an engine installed, Rexx can be used for scripting and macros in programs that use a Windows Scripting Host ActiveX scripting engine (such as VBScript or JScript).
The Franklin REX-PRO5 (pen is for size comparison). The back of the device. The Franklin REX 5, (also known as the “Rex-Pro”, as the “Rex 5000”, and with cosmetic variation as the “Rex 5001”) was one of the Rex line of Personal Digital Assistants, each a PCMCIA PC card and thus the size of a credit card, built around a Toshiba microprocessor emulating a Zilog Z80.
Object REXX is a high-level, general-purpose, interpreted, object-oriented (class-based) programming language.Today it is generally referred to as ooRexx (short for "Open Object Rexx"), which is the maintained and direct open-source successor to Object REXX.
Firmware hacks usually take advantage of the firmware update facility on many devices to install or run themselves. Some, however, must resort to exploits to run, because the manufacturer has attempted to lock the hardware to stop it from running unlicensed code. Most firmware hacks are free software.
REX is not POSIX compliant or open-source software and requires a proprietary software license from Qualcomm for use. [3] It seems not to be actively developed or marketed as of 2012, but is used in currently or recently sold low end cell phones, typically for use by pay-as-you-go customers, like the Samsung SPH-M300.
Rex is executed on the command line. Required parameters are fetched from the local Rexfile. The task logic is executed on the local host. The single commands of the specified task are executed atomically on every server. Rex may connect and execute commands in sequence or in parallel depending on the number of threads used.
