Description

This unit contains the predefined subprograms that convert between different Turing standard types. There are also six routines that are part of the language, rather than part of the unit, but are conceptually part of this unit. All routines in the TypeConv unit are exported unqualified. Description of the routines in the TypeConv module can be found in this chapter.
