Description

Int64Rec declares a utility record to provide access to the bytes of an Int64 value.

The Int64Rec type declares a utility record that stores 8 contiguous (packed) bytes of data. Int64Rec is used primarily for typecasting, where Int64 data needs to be analyzed.

The 8 bytes may be accessed individually through the Bytes array, or as an array of 4 Words, or as one of 2 Cardinals. Also, the value may be accessed through the Hi and Lo order Cardinals.
