%Tll/cc

This command positions the cursor at line ll, column cc on the next screen output.

The line and column positions are counted beginning with 1 within the current logical page. For this reason, the message line, the function-key lines, and the statistics line/infoline (if active) are not taken into account for the cursor position; that is, %T1/1 always positions to the beginning of the topmost data line of the page (if visible).

You have to execute the terminal command %T+ before you can place the cursor at any desired position on the screen.

%Tll/cc only works if there is an input field (session parameter AD=A or AD=M) at the specified position.
