Expressions
If expression is a literal expression, ZWRITE evaluates the expression and writes the resulting value on a separate line. If the expression contains an undefined variable, InterSystems IRIS issues an <UNDEFINED> error.
If the expression is a multidimensional property, ZWRITE will not display the property descendents. To display an entire multidimensional property with ZWRITE, either MERGE it into a local array and display the array, or display the entire object.
