SUMMARY

The information about the WINDOW statement in the online help system of QBX.EXE is incomplete. This article contains the correct documentation.

MORE INFORMATION

The online help system for the WINDOW statement in QBX.EXE currently reads:

y1!, y2!, x1!, and x2! are single-precision expressions specifying the top, bottom, left, and right sides of the window, respectively.

This statement is true if the WINDOW SCREEN statement is used, but is incorrect if the SCREEN option is left out. In keeping with the wording used in the online help, the following statement is the correct documentation for the WINDOW statement:

If WINDOW SCREEN is specified, y1!, y2!, x1!, and x2! specify the top, bottom, left, and right sides of the window, respectively. If just WINDOW is used, y1!, y2!, x1!, and x2! specify the bottom, top, right, and left sides of the of the window, respectively.

In other words, WINDOW SCREEN specifies the upper-left and lower-right coordinates for the window, with the Y value increasing from the top of the physical screen to the bottom (going down). Without the SCREEN clause, WINDOW specifies the lower-left and upper-right coordinates for the window, with Y increasing from the bottom to the top of the physical screen (going up).
