Packed Variables

A packed variable is the element of a packed array or the field of a packed record.

Table 5-2 “Allocation and Alignment of Packed Variables (HP Pascal Packing Algorithm) ” shows how the HP Pascal packing algorithm allocates and aligns packed variables of each HP Pascal type. The variable types are in alphabetical order. The sections that Table 5-2 “Allocation and Alignment of Packed Variables (HP Pascal Packing Algorithm) ” references are in this chapter.
