WAVE environment variables

 WAVE uses many environment variables; they are listed in this section roughly in order of importance. Many of them need not be set at all, since WAVE uses reasonable default values in most cases. Those that are set must be set on the WAVE host.  For general information on how to set environment variables, see the discussion of the DISPLAY variable.

  

DISPLAY

The name of the X server and display you are using (see the worksheet). If not set, WAVE will not be able to open windows on your display unless your display is attached to the WAVE host directly (not via network connection).

  

DB

The database path (see setdb(1), in the ECG Database Applications Guide. If not set, WAVE can find database files only in the current directory (on the WAVE host).

  

DBCAL

The DB calibration file (see setdb(1) and dbcal(5), in the ECG Database Applications Guide, and Calibration). If not set, WAVE may not scale signals other than ECGs correctly.

  

WAVEMENU

The name of WAVE's menu file). If not set, WAVE uses wavemenu in the current directory if possible; otherwise, it uses WAVE's default menu ($MENUDIR/wavemenu.def).

     

SHELL

The command interpreter used within the Analysis Commands window. If not set, WAVE uses /bin/sh (the Bourne shell). Other shell-related variables, such as PATH, are also significant when WAVE is running commands within the Analysis Commands window.

  

EDITOR

The name of the text editor to be used for modifying WAVE's menu file. If not set, WAVE uses textedit.

   

PRINTER

The name of a PostScript printer accessible to the WAVE host, to be used for paper output. If not set, WAVE uses the default printer.

  

PSPRINT

 The command needed to print PostScript from the standard input. If not set, WAVE uses the command lpr (or lpr -P$PRINTER, if PRINTER is set).

  

TEXTPRINT

The command needed to print ordinary text from the standard input. If not set, WAVE uses the command lpr (or lpr -P$PRINTER, if PRINTER is set).

   

ANNTAB

The name of a file that contains custom annotation definitions (see the discussion of Wave.Anntab for details). If not set, WAVE uses standard annotation definitions only.

The environment variables below are not needed unless the WAVE binary distribution, or XView,  has been installed in non-standard directories:

   

HELPPATH

The path for XView spot help; if not set, WAVE initializes it to /usr/lib/help. WAVE's own spot help is in $HELPDIR/wave, which is appended to the end of HELPPATH by WAVE.

  

HELPDIR

The directory in which WAVE's help directory is located; if not set, WAVE uses /usr/local/help.

  

MENUDIR

The name of the directory that contains WAVE's default menu file; if not set, WAVE uses /usr/local/lib.

  

RESDIR

The name of the directory in which system-wide default X11 resource files are kept; if not set, WAVE uses /usr/lib/X11/app-defaults. See the man page for WAVE for information about other directories that are searched for resource files.
