Adapting MIDAS to your personal needs
</H1>
<P>
There are commands in MIDAS which help you in tailoring MIDAS
to your personal taste and needs. <BR>
Maybe the most important one is
<TT>CREATE/COMMAND</TT> with which you can add abbreviated and alias command
names. As a next step, try out <TT>CREATE/DEFAULTS</TT> in order to set up your
own defaults for frequently used commands, e.g. size and location of display
and graphics windows in an X11-environment.
The command <TT>SET/MIDAS_SYSTEM</TT> has an extended set of options to let
you change internal MIDAS features, ranging from selecting your preferred text
editor (to be used e.g. in <TT>REPORT/PROBLEM</TT>)
to choosing your own MIDAS prompt.
With the command <TT>SET/BUFFER</TT> you modify the size of the internal command
buffer.
<BR>
If you have a MIDAS command procedure named `<TT>login.prg</TT>' in the
directory specified by MID_WORK, this procedure will be
automatically executed whenever you get into the MIDAS environment,
i.e. when you type <TT>INMIDAS</TT> (<TT>inmidas</TT>) or
<TT>GOMIDAS</TT> (<TT>gomidas</TT>).<A NAME="2615"> </A>
Therefore, the procedure <TT>login.prg</TT><A NAME="2617"> </A> is the place where you should put all
the commands needed to adapt MIDAS.<BLOCKQUOTE>

MIDAS prompt to <TT>Mid22</TT>, use `<TT>vi'</TT> as editor when you run the
<TT>REPORT/PROBLEM</TT> command, define the commands <TT>RK, WK, RD, WD, XH,
SMOOTH/SPECIAL</TT>, and override the preset defaults for <TT>CREATE/GRAPHICS,
CREATE/DISPLAY</TT>. Setting the environmment to <I>midhost</I> means, that
all commands which MIDAS does not understand are passed on to the host system.
Thus, instead of <TT>$ls</TT> you can directly enter <TT>ls</TT> at the MIDAS
prompt. Also, the user level is set to <TT>USER</TT>; cf. the following
section.
