string

The string function converts an argument {obj} into a String object.
If the argument is a native data type such as: #void, Error, Boolean, Character,
Integer, Number, Integer, Money, Percent, Text, or Character, the string
function converts the native data type into a String. Complex and String data types
are also converted into a String. If the argument is any other heap object such as
Symbol, Pair, Vector, Structure, or Dictionary, the string function returns
the object's external object id, i.e. #<Vector 1234>.
If the optional {true} argument is specified, the string function will
attempt to convert the object into the same external display string as the
writeln function.
The string function converts a complex number into to a string.
Usage The string function is used to coerce an object into a String or Text.
Any character string that is 15 characters is assigned to a Text data type.
If a character string containing more than 15 characters is assigned to a
String object.
The string function is used for displaying complex numbers.
