Block Mode Operation
6530 Programmer’s Guide 3-17
If the cursor is moved right or down into a protected field, the 6530
forward tabs, placing the cursor in the first position of the next
unprotected field.
If the cursor is moved up into a protected field, the 6530 back tabs,
placing the cursor in the first position of the previous unprotected
field.
If the cursor is moved left into a protected field, the 6530 first back
tabs the cursor to the previous unprotected field and then moves it to
the last column of that field.
The search for an unprotected field wraps around the page if necessary. If
no unprotected fields exist on the page, the cursor is not displayed.
Cursor Up (Esc A)
The Esc A sequence moves the cursor up to the previous row, while
maintaining the same column position. If the cursor is initially in row 1,
the cursor wraps to the last row of the page.
In protect submode, if the new cursor position is protected, a back tab
operation occurs.
Line Feed (LF)
The LF control character (0AH) moves the cursor down one row, while
maintaining the same column position. If the cursor is initially in the last
row, the cursor wraps to the top row of the page.
In protect submode, if the new cursor position is protected, a forward tab
operation occurs.
Cursor Right (Esc C)
The Esc C sequence moves the cursor one column position to the right. If
the cursor is initially in the last column, the cursor moves to the first
column of the next row. If the cursor is initially in the last column of the
last row, the cursor wraps to the first column of the first row.
In protect submode, if the new cursor position is protected, a forward tab
operation occurs.
