[Xerte] Trying to create a function with arguments

[Paul Swanson]

I'm trying to create a function in Xerte that will display HTML
entities. The function takes the normal HTML entity name, and should
return the unicode equivalent, so I need to pass it an argument.

>From the Help, I see that Xerte does not recognize the keyword
'function' so I'm confused on how to pass it an argument. Here is the
function (found it through Google, then added some missing entities that
I think I might use someday):

// create the entity mapping array     
// which allows decoding html entities into their unicode equivalents


function GetEntityArray(entity) {
    aryEntities = Array();
    aryEntities[" "]   = "\u00A0"; // non-breaking space
    aryEntities["¡"]  = "\u00A1"; // inverted exclamation mark
    aryEntities["¢"]   = "\u00A2"; // cent sign
    aryEntities["£"]  = "\u00A3"; // pound sign
    aryEntities["¤"] = "\u00A4"; // currency sign
    aryEntities["¥"]    = "\u00A5"; // yen sign
    aryEntities["€"]   = "\u20AC"; // Euro sign
    aryEntities["¦"] = "\u00A6"; // broken vertical bar (|)
    aryEntities["§"]   = "\u00A7"; // section sign
    aryEntities["¨"]    = "\u00A8"; // diaeresis
    aryEntities["©"]   = "\u00A9"; // copyright sign
    aryEntities["®"]    = "\u00AE"; // registered sign
    aryEntities["™"]  = "\u2122"; // trademark sign
    aryEntities["°"]    = "\u00B0"; // degree sign
    aryEntities["±"] = "\u00B1"; // plus-minus sign

    aryEntities["µ"]  = "\u00B5"; // micro sign
    aryEntities["¼"] = "\u00BC"; // vulgar fraction one quarter
    aryEntities["½"] = "\u00BD"; // vulgar fraction one half
    aryEntities["¾"] = "\u00BE"; // vulgar fraction three
quarters
    aryEntities["¿"] = "\u00BF"; // inverted question mark

    aryEntities["♣"]  = "\u2663"; // Club suit / shamrock
    aryEntities["♥"] = "\u2665"; // Heart suit / valentine
    aryEntities["♦"]  = "\u2666"; // Diamond suit
    
    return aryEntities[entity];     
}

When I try to use the function to set a variable, I get 'undefined.' Any
pointers? Incidentally, I think this would be a really useful addition
to the core Xerte.
