ViewMAX

ViewMAX is a CUA-compliant file manager supplied with DR DOS versions 5.0 and 6.0. It is based on a cut-down runtime version of Digital Research's GEM/3 graphical user interface modified to run only a single statically built application, the ViewMAX desktop. Support for some unneeded functions has been removed whilst some new functions were added at the same time. Nevertheless, the systems remained close enough for ViewMAX to recognize GEM desktop accessories (.ACC executables) automatically and to allow some native GEM applications (.APP executables) to be run inside the ViewMAX environment (without having to install and launch GEM first). Many display drivers for GEM 3.xx could be used by ViewMAX as well, enabling ViewMAX to be used with non-standard display adapters and higher resolutions than possible using the default set of ViewMAX drivers. Also, Digital Research's SID86, the symbolic instruction debugger that shipped with DR DOS 3.xx and provided dedicated functions to debug GEM applications (see ?Y GEM-specific help under SID86 or GEMSID), could be used for ViewMAX as well.
