4.8.1.10 WindMin variable

Targets: MS-DOS, OS/2, Win32 console

CRT Unit

Stores the screen coordinates of the current window.

Declaration:

var WindMax: Word;

Remarks:
These variables are set by calls to the Window procedure. WindMin VAR defines the upper left corner. WindMax defines the lower right corner.

The X coordinate is stored in the low byte, and the Y coordinate is stored in the high byte.

For example,

  Lo(WindMin)

produces the X coordinate of the left edge, and

  Hi(WindMax)

produces the Y coordinate of the bottom edge.

The screen's upper left corner corresponds to (X,Y) = (0,0), but for coordinates sent to Window and GotoXY, the upper left corner is at (1,1).
