rodry has asked for the wisdom of the Perl Monks concerning the following question:

I have a script that will construct a link to another PERL script and pass it parameters based on a column returned by a query.
There is a problem however. This column that I am passing as a parameter may or may not have spaces in it. More than likely it will have spaces.
So my question is: how do I detect this spaces and replace them with the appropiate ASCII character code.
As an alternative, how do I filter the user input when providing values for this column so that it will eliminate the spaces, if any?
Thanks in advance
