A :-separated list of directories used to search for
scripts filenames that do not begin with /, ./ or ~.
If this variable does not exist, a compiled value
is used. Typically compiled in value is:
.:./lib:~/lib:${LIBDIR}/calc
where ${LIBDIR} is usually:
This value is used by the READ command. It is an error
if no such readable file is found.
On startup (unless -h or -q was given on the command
line), calc searches for files along the :-separated
$CALCRC environment variable.
If this variable does not exist, a compiled value
is used. Typically compiled in value is:
${LIBDIR}/startup:~/.calcrc
where ${LIBDIR} is usually:
Missing files along the $CALCRC path are silently ignored.
On startup (unless -h or -q was given on the command
line), calc reads key bindings from the filename specified
in the $CALCRC environment variable. These key bindings
are used for command line editing and the command history.
If this variable does not exist, a compiled value is used.
Typically compiled in value is:
where ${LIBDIR} is usually:
If the file could not be opened, or if standard input is not
a terminal, then calc will still run, but fancy command line
This value is taken to be the home directory of the
current user. It is used when files begin with '~/'.
If this variable does not exist, the home directory password
entry of the current user is used. If that information
is not available, '.' is used.
When invoking help, this environment variable is used
If this variable does not exist, a compiled value
is used. Typically compiled in value is something
such as 'more', 'less', 'pg' or 'cat'.
When a !-command is used, the program indicated by
this environment variable is used.
If this variable does not exist, a compiled value
is used. Typically compiled in value is something
