Description

LongRec declares a utility record to provide access to the bytes of a LongWord value.

The LongRec type declares a utility record that stores 4 contiguous (packed) bytes of data. LongRec is used primarily for typecasting, where LongWord data needs to be analyzed.

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