eval() operator

From v4.2.0, eval() takes a single string as an argument and evaluates it. Thus

if(MyBool){AttribX="$Name(parent)"}else{AttribX="$Name(grandparent)"};AttribY=eval($AttribX)

will set AttribY to the name of the current name's note or it's grandparent depending on the value of attribute MyBool by evaluating attribute AttribX.

The eval() operator also allows access to 2 properties - current TBX document's filename (sans extension) and app version) - that aren't available via action syntax:

eval(^docTitle^) - gives a value of "aTbRef" (note no '.tbx' extension)

eval(^version^) - gives "4.2.5" (note - you might want to prefix the return string with 'v' or 'v.' thus: "v.4.2.5")
