Don and Eet – Working for a living, as I do, in a virtual world I can bring some experience about whether or not it is a good idea to load an entire large file into virtual memory. I work with VAX/VMS. In VMS there are two major editors, EDT and EVE. EDT, the elder editor, only reads in a part of the file. EVE, the younger and more vigorous, reads the entire file into virtual memory. Keeping functions and features completely out of the picture, EDT opens and is ready for editing much sooner on larger files than is EVE. On the otherhand, once EVE has read in the file, it moves around it much more quickly. My least favorite thing to do in EDT is read in a large file and then goto the end of the buffer. Personally I prefer EVE. I know both _very_ well. While it may appear to be a waste of memory, keep in mind that a virtual memory, multitasking machine, need only keep some of the file actually in memory. The remainder, as necessary, can be paged to disk. My 2-cents. – Nelson …
