These are some things I believe to be true for the MPW tool, but I'd like a formal concurrence from someone - Matthias? If an error occurs during compilation, The Perl tool will return non zero {Status} to MPW. On completion of a Perl script the most recently evaluated item will be returned in {Status} just as it is in a Perl subroutine. The special hash %ENV stores environment variables from MPW. This hash is filled from all existing environment variables in MPW at the time of execution of the Perl script so that, for instance, $ENV(Worksheet) is the full pathname of the MPW worksheet. ***** Want to unsubscribe from this list? ***** Send mail with body "unsubscribe" to mac-perl-request@iis.ee.ethz.ch
