Syntax: /PACKD[ATA] [:number]
This option groups neighboring data segments. It functions like the Combine Contiguous Code (/PACKC) option, except that it combines data segments.
The <number> field specifies the maximum size of a data segment grouped by /PACKD; if you omit <number>, the maximum size defaults to 65,536. LINK386 stops adding segments to a group as soon as it cannot add another segment without exceeding <number>. At this point, LINK386 forms a new group. See Entering Numeric Arguments.
