Does anyone happen to know why applications are limited to 100 megabytes under system 7? If you try and change the suggested size to more than that it'll tell you not to do it. It's not something that needs to be done lots for a home use computer, but say you have 10,000 medical images, or run a library catalog system or anything with lots of data and you want it available fairly fast. It would be a useful feature to not limit the application size to 100 Mb. Do we wait for system 8? Mark Vivino mvivino@helix.nih.gov

While 10M is too strict a limit, 100M is a lot of memory. Nobody will have so much RAM (Well, at least not for the next 2 years, until the 64M chips go into mass production). Personally, I don't even have 100M of *Hard Disk* space. Even if you have 100M of spare Hard Disk space for virtual memory, I don't think you'll have a significant performance gain over a clever disk caching scheme (That's what B-Trees are for). Out of curiosity, I checked the maximal process size on our various UN*X machines. For two machines, it was around 32M, for one 10M and for one 256M. Matthias BTW: One reason for this limitation could be that the mac is "limited" to 128M of real memory, I believe.

I believe this came up before, and the answer was to manipulate the SIZE resource by hand. -- /============================================================================\ | Francis Stracke | My opinions are my own.

This is only a limitation of the "Get Info" dialog window of the Finder. You can open the SIZE resource yourself and change the memory partition. ----------------------------------------------------------------------- Jim Reekes, E.O. | Macintosh Toolbox Engineering | Sound Manger Expert Apple Computer, Inc. | "All opinions expressed are mine, and do 20525 Mariani Ave. MS: 81-EQ | not necessarily represent those of my Cupertino, CA 95014 | employer, Apple Computer Inc."
