SET

 The SET command allows you to set the current `context' or the
 current context database for your process.

 A `context' is a named set of values that tailors the DECset tools
 to a specific software development activity (for example, fixing
 bugs or implementing enhancements).

 The SET command line has one of the following forms, depending upon
 whether a context or a context database is being set:

      DECSET SET CONTEXT context-name [/DATABASE=database-file]

      DECSET SET DATABASE database-file

 DCL wild cards may not be used in either the context-name or
 database-file argument.

 The /DATABASE qualifier allows you to set a context that is defined
 in the specified database.  If the /DATABASE qualifier is missing,
 the value of the DECSET$CONTEXT_DB logical name is used; if this
 logical name is undefined, your SYS$LOGIN directory is searched for
 a file named DECSET$KNOWN_CONTEXTS.DECSET_CONTEXT_DB.  If a database
 cannot be located, an error message is displayed.

 The DECSET SET CONTEXT command automatically defines the logical names
 DECSET$CONTEXT and DECSET$CONTEXT_DB.  The DECSET SET DATABASE command
 automatically defines the logical name DECSET$CONTEXT_DB.
