Midas 003 > The built-in decompression table is ignored and overwritten by another user-defined ta- ble in a file pointed by the environment variable DECOMPRESS TABLE if it exists, otherwise in a MIDAS-defined table located in the file /midas/11SEP/incl/decompress.dat if it exists. The syntax of these two files is described in the header of the /midas/11SEP/incl/decompress dat file, which could also be used as a template. 2.14 Access to printer-devices in MIDAS Printer-devices in MIDAS are used to print out text, graphics (plots) and images loaded onto the display window of MIDAS. In order to ease the installation a number of generic defini- tions of printer-devices used by MIDAS are defined in the file /midas/11SEP/monit/devices.sh , like: 11

LPRINT for the main line printer (text output only) LASER for Postscript b+w laser printer PLASER has to be the same as LASER !! COLOUR for Postscript color laser printer SLIDE for film recorder (slides) PENPLOT for a pen plotter (HP Graphics Language format) You have to edit this file and assign the printer system names to the logical names above (if existing at your site). Apart from these logical names also system names for printers can be used. However, the use of printer-devices for graphics output (plots) involves some extra installation work. A separate chapter, Chapter 3 Installation of Graphics Devices describes in detail how extra devices for graphics can be added. 2.15 Line editing in MIDAS The GNU readline is a public domain library widely supported on many UNIX platforms and enhances the line-editor capabilities of MIDAS like a history stack of commands, Emacs or Vi editing mode, command and filename completion functions and a communication channel with the MIDAS Graphical User Interface HELP for help-on-line functions. The editing mode by default with GNU readline is Emacs but it can be switched to mode Vi by setting the variable editing-mode to vi in the initialization file $INPUTRC if exists otherwise in the file $ HOME/.inputrc . As a brief introduction to GNU readline here is list of most common key-sequences: Self-insert CTR-L -> clear-screen CTR-E -> end-of-line CTR-A -> beginning-of-line CTR-U -> unix-line-discard CTR-K -> kill-line TAB -> complete TABs -> possible-completions CTR-X -> (also F1) on-line-help through the GUI HELP More detailed information about editing commands with GNU readline in the man-page /midas/11SEP/system/unix/readline.l Please, note, that you need the development version of the ncurses library for editing. 2.16 Stand-alone MIDAS utilities Chapter 5 Tapeserver Installation and Chapter 6 Other MIDAS Utilities describe the stand-alone MIDAS utilities, that is, programs that run, outside a MIDAS session, at 12

the system level. These are optional programs located in the /midas/11SEP/util directory and are not included in the standard installation of MIDAS.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
