HTX commands that need to display documents do so using a WWW browser and will try to make use of one that you already have running, if possible. Otherwise a new one will be started. By default, the Netscape browser will be used and will be invoked using the command:
netscape
You can change this command, or cause HTX to invoke the Mosaic browser instead if you prefer, by means of the HTX_BROWSER environment variable. Thus, if you normally use the command "Mosaic" to invoke your browser, you could put the following into your .login file:
setenv HTX_BROWSER Mosaic
Note that this command should not be an alias (e.g. if you normally use the C shell).
Currently, HTX can work only with Mosaic and Netscape -- and
it has to know which one you are using. To determine this, it searches
for either of the strings "mosaic" or "netscape" in the value
you give for the HTX_BROWSER environment variable. You should therefore ensure that the
comand you use contains one of these strings.
