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 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 references are in
this chapter.
