Partha,
In the sample above there is code that does :
move 1 to cursor-row
move 1 to cursor-column
to set the cursor position for the next ACCEPT. As those values do not correspond to a position of a value that can be modified within the screen the cursor will be positioned on the first field e the name field. If you wanted to set it on a specific field, for example the address field, you would move 7 to cursor-row and 10 to cursor-column.
