Unpacked Variables

An unpacked variable is either not part of an array or record, or it is part of an unpacked array or record.

Table 5-1 “Allocation and Alignment of Unpacked Variables (HP Pascal Packing Algorithm) ” shows how the HP Pascal packing algorithm allocates and aligns unpacked variables of each HP Pascal type. The variable types are in alphabetical order. Sections that Table 5-1 “Allocation and Alignment of Unpacked Variables (HP Pascal Packing Algorithm) ” references are in this chapter.
