Declaration

Source position: sysutilh.inc line 45

  case Integer of

    0: (

        Hi: Word;

Description

LongRec can be used to extract the parts of an long Integer: the high and low word, or the 4 separate bytes as a zero-based array of bytes. Note that the meaning (or ordering) of High and Low parts are different on various CPUs, and may differ from what is shown in the declaration: the ordering depends on the endianness of the CPU.
