#define CONVERT_CAN_CHAR

Define for each data format if a conversion is needed from the local format to the canonical format (or vice-versa).

This allows for optimizations in, for example, AipsIO. The canonical format is ASCII for strings, IEEE for floating point and 2-complement for integers (all most significant bit first) with the lengths as shown above. The function checkConvert() can be used to check if the flags are set correctly.

Conversion is needed for little endian architectures (like DEC and Intel), because the bytes have to be swapped (thus not for data with length 1).

#define SIZE_CAN_CHAR

Define the canonical sizes of the built-in data types.

These are the same for all machine architectures. Also define the maximum size.
