18.4.9 Resequencing a Task

The

method

used to resequence tasks in the

PC Monitor

is the same

as the method used in the PC Editor, except for the fact that tasks

resequenced in the PC Monitor are running and the change takes

effect with the next scan.

To resequence a task, follow the directions below.

1. Type F3 followed by R" for Resequence.

2. At the prompt Old First Sequence", enter the sequence number

at which you want to begin the resequence.

3. At the prompt Old Last Sequence", enter the upper limit for the

range of sequences you want to resequence. The range you

select is inclusive.

4. At the prompt New First Sequence", enter the new sequence

number for the first sequence in the range.

5. At the prompt New Increment", enter the number to add to

subsequent sequence numbers, beginning with the New First

Sequence".

The following are not permitted when you resequence and will cause

the system to display an error message if attempted:

* If New First Sequence" is smaller than the sequence

immediately preceding Old First Sequence". For example, you

cannot resequence the sequences shown boxed on the left as

those shown boxed on the right:

cannot be resequenced as shown

*If

the new last sequence

in the range would become greater than

the

sequence that follows the Old Last

Sequence". F
