Description

The WROWS() function returns the number of rows in either the current window, or the window specified by <window-name>. A window is an area of the screen designated for output and input. There is no limit to the number of defined windows. Windows are created with the DEFINE WINDOW command, and are activated with the ACTIVATE WINDOW command. With no parameter, the WROWS() function returns the number of rows in the currently active window. If no windows are active, the WROWS() function returns a zero. If the window <window-name> is specified and does not exist, or is not active, the WROWS() function returns a zero.

Example

define window browse;
  from 2,2 to 12,43;
  title "BROWSE Window";
  color n/bg;
  float;
  shadow
activate window browse
? wrows("browse")
