... Context files provide a way to group commands which relate to a specific reduction sequence or application package. For example, the command SET/CONTEXT applic1 will execute the MIDAS procedure applic1.ctx , which would contain all the new command definitions for the application package applic1 as well as any new keyword definitions and default settings. Each enabled context has a corresponding context no. which links new commands to the context in which they were created. ...

. Next: Creating a filesystem Up: Filesystems Previous: Filesystems galore . There is usually little point in using many different filesystems. Currently, ext2fs is the most popular one, and it is probably the wisest choice. Depending on the overhead for bookkeeping structures, speed, (perceived) reliability, compatibility, and various other reasons, it may be advisable to use another file system. This needs to be decided on a case-by-case basis. Lars Wirzenius . Sun May 4 14:08:43 EEST 1997
