Synopsis

This class contains static toLocal functions to convert data from IBM-360 format to local format and vice-versa. It also handles the conversion of the IBM EBCDIC characters to ASCII characters (for data type char).

The functions work well on big-endian as well as little-endian machines.

Motivation

Archived WSRT data can be stored in the old IBM format (EBCDIC characters and floats with base 16). Conversion functions are needed to read these data.

To Do

• Support data type long double.

Member Function Documentation

static void casa::IBMConversion::fromLocal	(	void *	to,
		char	from
	)		[static]

Convert one value from local format to IBM format.

The from and to buffer should not overlap.
Note: The char version converts from ASCII to EBCDIC, while the unsigned char version is a simple copy;
