3.2.29. $Z: Minimum enumeration size switch

(Targets: MS-DOS, OS/2, Win32)

$Z Compiler directive controls the minimum storage size of enumerated types.

Syntax:

  {$Z1} or {$Z2} or {$Z3}

Default:

  {$Z1}

Remarks: An enumerated type is stored as an unsigned byte since the maximum limit for enumeration is 256 values. If the {$Z2} switch has been specified, it is stored as an unsigned word. If the {$Z4} switch has been specified, it is stored an unsigned double-word. This feature is very useful for compatibility with C and C++ DLL's, which usually represent enumerated types as words or double-words.
