Description

ufne => Use First None Empty (parameter).

Checks a set of anonymous parameters and returns the first non empty one.

"{{{1|{{{2|{{{3|}}}}}}}}}" will not do that. As it returns the first defined one - empty or not.

Syntax

{{ufne|parm1|parm2|...|parm9}}

Basic use example

{{ufne| {{{named-parm-1|}}} | {{{3|}}} | {{{named-parm-2|}}} | {{{2|}}} }}

Including the "{{...|}}" part is crucial here.

Limitation

Accepts & processes a maximum of 9 parameters.

Any parameters after nr 9 are ignored. No error message either.

Potential issue

Might not work with parm-data that contains a "=" character.
