AT Phrase

The AT phrase indicates the absolute address on the screen at which the ACCEPT operation is to start. If the AT phrase is not specified, the ACCEPT operation starts at line 1, column 2. It does not indicate the starting position of the leading attribute.

The LINE phrase specifies the line at which the screen item starts on the screen.

The COLUMN phrase specifies the column at which the screen item starts on the screen.

COL is an abbreviation for COLUMN.

The LINE and COLUMN phrases can appear in any order.
identifier-2, integer-1
Identifier-2 and integer-1 must be an unsigned numeric integer with a value greater than or equal to zero and less than 9 digits. If the value for LINE or COLUMN is negative, the absolute value is taken. Identifier-2 or integer-1 is moved into a PIC 9(3) number.

Identifier-2 cannot be an internal or external floating-point data item.

Certain combinations of line and column numbers have special meaning:
identifier-3, integer-2
Identifier-3 must be a PIC 9(4) or a PIC 9(6) field. Identifier-3 cannot be an internal or external floating-point data item.

Integer-2 must be a 4- or 6-byte numeric field.

If identifier-3 or integer-2 is 4 digits long, the first 2 digits specify the line, and the second 2 digits specify the column. If identifier-3 or integer-2 is 6 digits long, the first 3 digits specify the line, the second 3 digits specify the column.
