MIDAS is a command driven system in which the user enters commands
followed by parameters. This implies that the user must know a few
commands and their structure in order to make effective use of the
system. Since most users cannot keep all the commands and their parameters
at their finger tips, an extensive on--line help facility has been created as
well as a printed version of the help text (see the Appendices).
A MIDAS command has the following structure:
COMMAND/QUALIFIER par1 par2 ... par8
where par1 is the first parameter and so on. The important points are:
- Command and qualifier are separated by a / (slash).
- The command/qualifier and the parameters are separated by a
space.
- Most commands have qualifiers.
- A parameter may contain several sub-parameters which are separated by
commas.
- In most cases if the parameters are not specified, the system
makes sensible defaults, but the user should not always trust these
default values to be those he might have chosen.
- Keep these rules in mind, otherwise you will confuse the command.
MIDAS commands divide themselves into three categories:
- MIDAS primitive commands
- MIDAS application commands
- procedure control commands
The MIDAS commands are listed in alphabetical order and explained in
detail in Volume C of the MIDAS User Guide. The
application commands are developed for special purposes such as CCD or
CASPEC reductions. They are described and listed in the various
sections related to particular applications. For reductions of data
you should refer to Volume B of this manual. The procedure control
commands are described in Chapter .
