These environment variables are referred to by the runtime system.
- Directory in which to look for init files. E.g. c:\users\joe
or /home/joe. Under Windows, the environment variables
HOMEDRIVE and HOMEPATH, set by the operating system, are
used instead. Under unix, HOME is set by the login shell.
- Directory for various temporary files. The variables are tried in the
given order. If none of them is suitable, built-in defaults are used:
under unix, /var/tmp, /usr/tmp, /tmp; under
Windows, \temp, \tmp, and \ (all on the system
- Directory containing the debugging information files for the Scheme
system. Should contain subdirectories corresponding to the
subdirectories in the source tree. For example, if its value is
f:\random, runtime system debugging files will be expected in
f:\random\runtime, while Edwin debugging files will be expected
in f:\random\edwin. By default, the information is searched
for on the library path.
- Specifies the location of the options database file used by the
load-option procedure. The default is optiondb.scm on
the library path.
