Once such an application is loaded, to switch to it, Windows merely need switch a few CPU registers and handle the FAT when file read writes are made. Programs can pass data very effectively to each other, and to Windows applications, by way of a file, which is very convenient particularly if the data is being stored to a file anyway.
The standard software shipped with each RM system (Aw-srad.exe) draws very nice full color scrolling bar charts in Text Mode, which Windows can very rapidly insert into a shrunken Window, using a smaller Windows font. In fact, Aw-srad.exe's display is so effectively placed in a window by Windows, it might generate one of the fastest scrolling graphs seen in Windows. (Choose Auto speed scroll) Aw-graph draws in VGA mode (or EGA, CGA, Herc, etc.), but Windows seems very speedy at updating a window display of Aw-graph as well, particularly if you tell Aw-graph to make a little bit smaller graph, as are those displayed above.
Aw-srad.exe size: ~ 79K. Aw-graph.exe size ~ 170K, so both programs run very effectively not only on the most advanced PC but also from an XT with just one floppy drive or on a Palm Top like the LX200 from H.P.
