#define CONVERT_LECAN_CHAR

Define for each data format if a conversion is needed from the local format to the little endian 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 last) with the lengths as shown above. The function checkConvert() can be used to check if the flags are set correctly.

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