Moving or positioning the work file
&pagelevel(3)&pagelevel
The following statements, which are primarily used in F mode, make it possible to move the required section of a work file into the screen for processing.
+ | Moves forwards in the work file (toward the end of the file).
The position can be moved forwards by a given number of
lines or to a record with a specified record mark. | F mode |
- | Moves backwards in the work file (toward the beginning of
the file). The position can be moved backwards by a given
number of lines or to a record with a specified record mark. | F mode |
++ | Moves to the end of the work file or to the last record with a
specified record mark. | F mode |
- - | Moves to the beginning of the work file or to the first record
with a specified record mark. | F mode |
< | Moves horizontally to the left in the work file, i.e. the data
window can be moved through column-by-column to the left
(toward the start of the record). | F mode |
> | Moves horizontally to the right in the work file, i.e. the data
window can be moved through column-by-column to the
right (toward the end of the record). | F mode |
<< | Moves horizontally to the start of the record in the work file,
i.e. the data window is moved through column-by-column to
the start of the record. | F mode |
# | see @SETF statement | F mode |
@END | In L mode, causes the current work file to be exited.
Processing returns to the work file in which the @PROC
statement activating the current work file was issued. In F
mode, @END terminates the EDT session. | F mode
L mode |
@ON (Format 3) | Causes all records in which a hit is identified to be flagged
with the specified record mark. In F mode, the work window
is positioned at the first hit record. | F mode
L mode |
@PROC (Format 1) | In L mode, switches to another work file. This work file then
becomes the current work file. | L mode |
@SETF | Simultaneously sets the vertical and horizontal position of
the work window for a work file either with or without
changing the current work file. In F mode, this statement
may be abbreviated to # (if specified with operands). | F mode
L mode |
0..22 | Switches to another work file. | F mode |
$0..$22 | Switches to another work file. | F mode |
