Monitor and Command Language
</H1>
<P>
This chapter is organised as follows:
<UL>
<LI>In the first two sections we describe how to start MIDAS and how
the host operating system and MIDAS coexist.
<LI>Section 3 explains the different data structures used in MIDAS and how
to access them in a MIDAS session.
<LI>Section 4 describes the syntax of the MIDAS commands, as well as
the editing and recalling of commands and also the on-line HELP
facility in MIDAS.
<LI>In section 5 you will find some details about how the MIDAS commands
are executed.
<LI>Then follows the largest and most detailed section (section 6),
which gives
in-depth information about the MIDAS command language, <TT>MCL</TT>.
<BR>
With <TT>MCL</TT> you can write high level MIDAS ``programs'' which
are called MIDAS procedures.
<BR>
The topics include:
<UL>
<LI>the <TT>MCL</TT> commands
<LI>passing parameters in MIDAS procedures
<LI>symbol substitution
<LI>loops and conditional branching
<LI>special functions
</UL>
<LI>Section 7 introduces the MIDAS contexts.
<LI>Section 8 explains how to run application programs written
in FORTRAN or C inside MIDAS. It also shows how to debug
these programs as well as MIDAS procedures.
<LI>All the commands related to MIDAS
catalogs are listed in section 9, together with an example of how to use
catalogs in MIDAS procedures.
<LI>The MIDAS login procedure and MIDAS user levels are the topics
of the last two sections.
</UL>
<P>
The MIDAS directory tree structure is not covered in this chapter.
For those interested, please refer to the <I>MIDAS Environment document</I><A NAME="1309"> </A>.
