unit VirtualKeysAlphanumeric;

// Purpose: Explicitly defines Virtual Key constants for A-Z and 0-9
//          using the Ord() function.
//
// Usage:   Include this unit in your 'uses' clause, preferably early
//          if you suspect conflicts with other units (like third-party
//          libraries or potentially modified standard units) defining
//          these constants differently or incompletely.
//
// Note:    This unit ONLY defines VK_A..VK_Z and VK_0..VK_9. For other
//          virtual keys (VK_SHIFT, VK_ESCAPE, VK_F1, etc.), you still
//          need to include and rely on the standard Winapi.Windows or
//          System.UITypes units.
