507# Note: Use of Cwd::chdir() causes the logical name PWD to be defined
508# in the process logical name table as the default device and directory
509# seen by Perl. This may not be the same as the default device
510# and directory seen by DCL after Perl exits, since the effects
511# the CRTL chdir() function persist only until Perl exits.
