SUMMARY

CENTMESS(), the user-defined function (UDF) shown below, centers a message in a row or column. CENTMESS() subtracts the length of the message from the length of the output area, divides the results by 2, and displays the message at the passed row and computed column.

If a message is being sent to a window:

Use WCOLS() to return the number of columns in a window.
Use WROWS() to return the number of rows in a window.

For example, to center an output message in the last row of a window, you would use the following syntax:

   =CENTMESS(WROWS()-1,WCOLS(),"This is the message to center")

MORE INFORMATION

   * In the following example, the output area is the desktop.

   SET CURSOR OFF
