Parameters

Keyword Type Description

typeNumber

The type number to be inquired for its name. This may be retrieved by using typeof(x), where x is a value of the intended type, or referencing a type with 'type!{namespace}type-name' (within single quotes).

Returns

Text

Usage considerations

Referencing data types

  • To retrieve the type number, use typeof(x), where x is a value of the intended type, or reference a type with type!{namespace}type-name (within single quotes).
  • When referencing a data type, consider the impact that deleting the data type has on the expression that references it.
