Return

Row() returns an integer numeric value in the range of zero to MaxRow() indicating the screen row where the cursor is found.

Description

The screen function Row() indicates the row where the cursor is located. The internal variable whose value is returned by the function Row() is changed by all screen oriented output functions and commands, except the function RestScreen().
