    Luc, Unless I'm wrong the return of those will be a number. What I wan´t is something to return 'true' or 'false', depending if the expression if true or false. Something that checks if a string is part of "Filter"


    Function('23234','23*') would return true

    Is this possible?

    Use Microsoft Script Control.

    VariantVal : Variant
    Script: Automation 'Microsoft Script Control 1.0'.ScriptControl"

    CREATE(Script);
    Script.Language := 'VBScript';
    VariantVal := Script.Eval('2+5>=5');
