This chapter assumes that the environment variable PATH includes
<prefix>/bin, where <prefix> points to the SICStus
installation directory. The installation directory is specified during
installation; see UNIX installation. For example:
csh,tcsh> setenv PATH "/usr/local/sicstus4.2.3/bin:$PATH"
sh,bash,ksh> export PATH="/usr/local/sicstus4.2.3/bin:$PATH"
