[Orca-users] Re: Date_parse routine usage

[Mike Shannon]

Blair,

thanks for the data

I am a Perl 4 guy
so some of the things you have here are new to me
if it is okay could you explain some of them?

the my command
what parsesdate ($string) does...

finally in the config file
what does the parse_date comand look like
(or are you saying put the sub right in the config file?)

thanks!!

mike
