Synopsis

This class is a specialization of the abstract base class DataConversion. It contains functions to convert data from/to the old IBM format using the static functions in class IBMConversion.

Example

See example in class DataConversion.

Motivation

This class is an addition to IBMConversion to be able to use the conversion functions in a polymorphic way.

To Do

Support data type long double.

Convert one value from IBM format to local format. The from and to buffer should not overlap. The char version converts from EBCDIC to ASCII, while the unsigned char version is a simple copy.
