1 DECset
DECset for OpenVMS VAX and OpenVMS Alpha is a set of layered products
that supports software developers' coding, debugging, testing, and
maintenance activities. These layered products are:
Code Management System (CMS) -- provides an efficient method for
storing project files and tracking all changes to those files.
CMS stores any kind of file including documents, plans,
specifications, status reports, source code files, object files,
executable images, sixel files and other kinds of files.
Language-Sensitive Editor (LSE) -- assists in developing
programs faster. LSE is a multilanguage programmer's editor.
LSE allows users to efficiently edit, compile, review diagnostic
information from compilations, and correct compile time errors
without exiting the editor.
Module Management System (MMS) -- automates and simplifies
the building of software applications. MMS can optimize the
build process by rebuilding only those components that have
changed since the system was last built.
Performance and Coverage Analyzer (PCA) -- helps users pinpoint
execution bottlenecks in application programs. PCA can also
identify which parts of an application are not executed by a
given set of test data.
Source Code Analyzer (SCA) -- aids programmers in understanding
the complexities of software systems. SCA allows users to
analyze an entire system, as opposed to individual components,
and helps users understand unfamiliar systems.
Digital Test Manager (DTM) -- automates the creation and
maintenance of regression tests. DTM also automatically
compares test run results with expected test results.
DECset Environment Manager -- provides a single mechanism for
tailoring the execution environment for a set of DECset tools.
The Environment Manager is used to define and switch between
software development activities in the DECset environment.
The products in the DECset environment can be used in either a
workstation or character-cell terminal environment. All DECset
components include both DECwindows Motif and command-line interfaces.
2 Commands
DECset commands pertain to the use of the DECset Environment Manager
in a character-cell terminal environment or in batch mode.
3 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.
3 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.
2 Context_File
A context file contains statements which assign values to the
various attributes comprising a context. This file may also contain
comment lines and blank lines.
A statement is used in the context file to assign a value to a
particular context attribute. A hyphen may be used in the last
character position of a line to continue a statement on the
following line.
Several of the statements that may appear in a context file are
similar to DCL commands; however, the syntax of these statements is
more restrictive than that of DCL.
Note that a context file is automatically generated when you save a
context via the Environment Manager's graphical user interface.

/PROCESS
/JOB
/GROUP

/TABLE.
3 DEFINE
The DEFINE statement is used to define a logical name.

DEFINE [qualifiers] logical-name equivalence-string[,...]
4 Qualifiers
The optional qualifiers for the DEFINE command are:
/PROCESS
/JOB
