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 which can be used within the Midas terminal window as well as via a graphical user interface.
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. 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.
