─────Packing Structures (/Zp)───────────────────────────────────────────────
 
     The /Zp option controls the packing of variables in structures.
 
     Syntax: /Zp[{1 | 2 | 4}]
 
     A tight pack saves memory space, at the expense of slightly slower
     access for noncharacter variables.
 
     By default, structures are packed according to the following
     rules: INTEGER*1, LOGICAL*1, and CHARACTER variables begin at the
     next available byte; all other variables begin at the next even
     byte.
 
     /Zp1 forces all variables to begin at the next available byte,
     whether odd or even.
 
     /Zp2 is the default packing.
 
     /Zp4 forces INTEGER*1, LOGICAL*1, and CHARACTER variables to begin
     at the next available byte, whether odd or even. All other
     variables start on the next four-byte boundary.
