- DSCRNSAV v1.2
-
- DSCRNSAV was originally written by David Markovitch, who I've never met
- or even corresponded with. My contribution has merely been to improve
- an already very useful program.
-
- DSCRNSAV is the smallest screen saver I've ever come across. It works
- by reprograming the video hardware to move the screen image around, thus
- not requiring any storage space for the screen. It works in all video
- mode on all the machines I've come across, including CGA, Herc, EGA and
- VGA screens. I've had one report of a machine on which it wouldn't
- work, and several of programs with seem to deactivate it.
-
- DSCRNSAV could probably be improved further. I leaves 256 bytes of PSP
- still resident, and doesn't release its environment. I may look at
- fixing this some other time. For smallest resident size, load it before
- you start defining environment string (including path and prompt).
-
- Version 1.1 recoded the installation software so that DSCRNSAV could
- find and control the resident copy when it was loaded high, and took
- the installation messages out of the resident section of code, reducing
- the TSR size by about 200 bytes.
-
- Version 1.2 allows selectable delays, taking a single command line
- parameter which specifies the delay. A parameter of zero disables the
- screen saver.
