After a recent reference to the /v switch in 4dos (undocumented), I was curious about what it was and got the following from one of the authors: >From: Tom Rawson >Date: 7/31/90 2:34PM Go ahead and post this to comp.windows.ms. The /V causes 4DOS to reserve space for its transient portion when it is in use, and free it when an application is loaded. This forces Windows to save 4DOS's transient portion when switching away from and back to a 4DOS window while at the prompt. Without /V, the transient portion is trashed and hitting a character at the prompt will hang the system. The problem will not occur when you are running an application within a 4DOS window, as the transient portion is swapped out at that point, and hence is preserved by 4DOS itself. The above does not apply to 386 enhanced mode, where Windows apparently does not trash 4DOS's transient portion. However use of /V in 386 enhanced mode won't cause any troubles either. ... Tom
