string   Description Syntax Examples Argument Types How do I contact the AIS team?

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. #. 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.

(string obj) (string obj true)

Here are a number of links to Lambda coding examples which contain this instruction in various use cases.

These examples show how an Integer, Character and Boolean object may be coerced into a String. The resulting Strings are the same Integer, Character or Boolean object but already with a String data type.

These examples show how the string function works with other heap objects such as Vectors. If {true} argument is specified the value of the object is returned instead of its external ID.

These examples show how the string function works with other heap objects such as Pairs. If {true} argument is specified the value of the object is returned instead of its external ID.

Here are the links to the data types of the function arguments.

Here are also a number of links to functions having arguments with any of these data types.
