Hi,

How can test whether a variable has been set? I couldn't find any reference to this in the wiki?

What do you mean by "set"? I use \doifnothing{\getvariable{foo}{bar}} {foo:bar contains nothing.\par}% \doifsomething{\getvariable{foo}{bar}} {foo:bar contains something.\par}% \doifelsenothing{\getvariable{foo}{bar}} {foo:bar contains nothing.\par} {foo:bar contains something.\par}% to test, if a defined(!) variable contains something. If you want to test if a variable is defined, you can use \doifnotvariable{foo}{bar} {foo:bar is undefined.\par}% \doifvariable{foo}{bar} {foo:bar is defined.\par}% \doifelsevariable{foo}{bar} {foo:bar is defined.\par} {foo:bar is undefined.\par}% Never used these macros, as I always define default values for my variables.
