in reply to Template Toolkit, Default and Zero

Quoting from the Template::Manual::Directives perldoc page on the DEFAULT directive:-

The DEFAULT directive is similar to SET but only updates variables that are currently undefined or have no "true" value (in the Perl sense).

The following seems to work though:-

[% UNLESS n.defined && n.length; n = 1; END %]

    Though not required, could this be turned into a MACRO?

    That worked nothing less that perfectly as a replacement for DEFAULT. Thanks.
