[…] any of the […] options can be "permanently" excluded at installation time (will also save the memory for the corresponding code excerpts due to our Dynamic Dead Code Elimination), or it can be disabled or enabled at any later time via API functions in case someone wants to keep a user from being able to reboot the machine. […] we are considering to add more synchronous cache flush calls […] Due to our Dynamic Dead Code Elimination method this would not cause any kind of bloating when not needed in a particular target configuration as a particular cache flush call would be included in FreeKEYB's runtime image only if the corresponding disk cache is loaded as well or FreeKEYB was told by command line switches to load the corresponding support.
[…] FreeKEYB builds the driver's runtime image at initialization time depending on the type of machine it is being loaded on, the type of keyboard, layout, country and code page used, the type of mouse and video adapter(s) installed, the other drivers loaded on that system, the operating system and the load and relocation method(s) used, the individual features included, and the configuration options specified in the command line. Due to the large number of command line switches and options supported […] (around fifty switches […] with multiple possible settings) there is a high number of feature combinations with uncountable dependencies […] resulting in […] endless number of […] different target images. FreeKEYB's Dynamic Dead Code Elimination technique manages to resolve […] these […] dependencies and […] remove dead code and data […] is not restricted to […] include or exclude a somewhat limited number of modules or whole sub-routines and fix up some dispatch tables as in classical TSR programming, but […] works […] at […] byte level […] able to remove […] individual instructions in the middle of larger routines […] distributed all over the code to handle a particular case or support a specific feature […] special tools are used to analyze the code […] and create […] fixup tables […] automated […] using conditional defines […] to declare the various cases […] not only optional at assembly time but at initialization time […] without the […] overhead of having at least some amount of dead code left in the runtime image […] to keep track of all the dependencies between […] these conditionals, dynamically build and relocate the runtime image, fix up all the references between these small, changing, and moving binary parts […] still allowing to use the tiny .COM/.SYS style […] model […] is done at initialization time […] API to import and export object structures between FreeKEYB and the calling application […] to transparently resize and move them internally […] at runtime […]
[…] brandneue[s] Feature, der dynamischen Dead-Code-Elimination, die die jeweils notwendigen Bestandteile des Treibers erst zum Installationszeitpunkt zusammenbastelt und reloziert, so daß keine ungenutzten Code- oder Datenbereiche mehr resident bleiben (z.B. wenn jemand ein bestimmtes FreeKEYB-Feature nicht benötigt). […](NB. This represents the first known implementation of byte-level granular dynamic dead-code elimination for software assembled or compiled ahead-of-time.)
[…] the loader will dynamically optimize the resident data areas and code sections at byte level to remove any redundancy from the driver depending on the given hardware/software/driver configuration and locale. […]
[…] Since FreeKEYB uses our dynamic dead-code-elimination to optimize its memory image for the target environment at load time, I would certainly like to add special support into FreeKEYB for GEOS which could be controlled by a command line option, so the extra code is only loaded when GEOS is used as well. […]
[…] I would be willing to add special hooks into FreeKEYB, our much advanced DOS keyboard driver, would it prove to improve the usability under GEOS […] Due to our sophisticated new Dynamic Dead Code Elimination technology which removes at byte level any code snippets unused in a particular given driver, user, or system configuration and hardware environment when the driver's installer builds and relocates the load image of itself, this would have no memory impact for non-GEOS users at all, so there's not much to worry about (memory footprint etc.) as in traditionally coded DOS drivers. […]
[…] Lazy evaluation is basically dynamic dead code elimination. […](NB. Possibly the first public use of the term dynamic dead-code elimination, though only conceptually and with a focus on lazy evaluation in functional languages.)

[…] a […] unique feature […] we call dynamic dead code elimination, so you can at installation time […] specify which components of the driver you want and which you don't. This goes to an extent of dynamic loadable modularization and late linkage I have not seen under DOS so far. If you do not like the screen saver, macros, the calculator, or mouse support, or <almost anything else>, you can specify this at the command line, and FreeKEYB, while taking all the dependencies between the routines into account, will completely remove all the code fragments, which deal with that feature and are not necessary to provide the requested functionality, before the driver relocates the image into the target location and makes itself resident. Removing some smaller features just saves a couple of bytes but excluding more complex components can save you half a Kb and more. You can also specify the size of the data areas […]
