SHOW

 The SHOW command is used to display either the description of a
 single `context' or the file specification of the current context
 database.

 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 SHOW command line has one of the following forms, depending upon
 whether information about a context or a context database is being
 shown:

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

      DECSET SHOW DATABASE

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

 If context-name is not specified in the DECSET SHOW CONTEXT command,
 the value of the DECSET$CONTEXT logical name is used (if that logical
 name is defined).  If the context name cannot be determined, an error
 message is displayed.

 The /DATABASE qualifier allows you to show information about 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.
