Important: Timers and counters cannot be separated into control, preset,
and accumulated value for the purpose of file transfers. In addition,
pointers cannot be separated into section, file, and word. Therefore, no file
number is necessary (although you can specify file 0).

For example, to add the timer section to the fifth position in the list, the
counter section to the sixth position, and the pointer section to the seventh
position in the list, type:

5/T

or

5/T0 [ENTER]

6/C

or

6/C0 [ENTER]

7/P

or

7/P0 [ENTER]

Figure 4.3 shows a rung for executing a continuous file transfer. It uses
integer file 2 and the timer section of the data table.
