Thank you, Andrew. Andrew, pointed out that Perl provides a way to delay the resolution of a method. >Date: Sun, 19 Aug 2001 20:04:12 -0700 (PDT) >From: Andrew Ho <[EMAIL PROTECTED]> > >George, > >>GS>In other words, I would like all my reference to be hard method >>GS>references which are developed from string scalars at run time (delayed >>GS>resolution and later dereferenced). >> >Perl allows you to delay resolution of a method until run-time: > > $method = 'foo'; > $object->$method($a, $b, $c) >Humbly, > >Andrew > >---------------------------------------------------------------------- >Andrew Ho http://www.tellme.com/ [EMAIL PROTECTED] NOTE: Above, I should have said "subroutine" in place of the word "method", since "method" implies OO referent calls. Also, I did not understand "delayed resolution". (My mistake.) I choose to implement the following (snip): no strict 'refs'; $Commands{$command}{cmd}=\&$routine; # $routine contains a string use strict 'refs'; unless(defined &{$Commands{$command}{cmd}}) { delete $Commands{$command}; # This is bad, so throw it away! warn "$routine routine is not defined"; } for a couple of reasons. 1) The methods are not OO (yet). 2) The above assignment only happens during initialization. [I learned a lot about OO Perl.] Again, thanks, [done] +=======================================+ | George Sanderson <[EMAIL PROTECTED]> | | <http://www.xorgate.com/>www.xorgate.com | +=======================================+
