1.3.1.1 Environment Variables

Before starting up casapy, you should set or reset any environment variables needed, as CASA will adopt these on startup. For example, the PAGER environment variable determines how help is displayed in the CASA terminal window (see § 1.3.8.3). The choices are less, more, and cat.

In bash, pick one of

   PAGER=less
   PAGER=more
   PAGER=cat

followed by

export PAGER

In csh or tcsh, pick one of

   setenv PAGER less
   setenv PAGER more
   setenv PAGER cat

The actions of these are as if you were using the equivalent Unix shell command to view the help material. See § 1.3.8.3 for more information on these choices. We recommend using the cat option for most users, as this works smoothly both interactively and in scripts.
