Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     A number of the screen routines specify the screen-position
     parameter. In this COBOL system, the top left corner of the screen
     is row 0, column 0. For example, if you want to change attributes
     beginning in row 5, column 8, you specify row-number as 4 and
     column-number as 7.
