Win 3.0 Enhanced mode has Standard/Real mode functions plus the option to designate a perminent swap file, whereby contiguous sectors on a disk are preallocated for use as a swap file. Temporary saves (i.e. *.tmp) are still stored in a designate temp subdirectory or the root directory (if a temp directory is not designated). A diskless workstation would have to set the swapfile option off or set a perminent swapfile to a RAM drive and designate a RAM drive subdirectory as a temp directory. Unless I am mistaken the swapfile and the temp files must be considered separately. I imagine that a swapfile remotely located would degrade apparent speed of operations more than a temp subdirectory remotely located. With limited RAM and large applications and/or numerous applications Win 3.0 would probably have to employ a swapfile more often than an application would have to employ a interim "save" file (i.e. a *.tmp file). In order of preference: 1) Disable swapfiles in enhanced mode or somehow establish a swapfile in a RAM drive (if possible and/or reasonable). 2) Designate a temp subdirectory located in a RAM drive for any Win 3.0 mode. You will use up RAM in either case but you will preclude excessive use of remote disk space. What happens if an application does not have enough temp space? I believe PageMaker displays error messages. Lack of swapfile space in enhanced mode usually prevents you from loading data or an application (out of memory). barry -- +--------------------------------------------------------------------+ | Barry B.
