|
||
|
|
<div><p>Using a single notify object for all programs is advantageous because
|
||
|
|
all information required to start again is in the same object and a standard
|
||
|
|
approach to the notify object can be used in all programs. In this situation,
|
||
|
|
use a unique combination of user and program identifications to make sure
|
||
|
|
that the program accesses the correct information when it starts again.</p>
|
||
|
|
<p>Because the information required to start again might vary from program
|
||
|
|
to program, do not use an externally described data structure for the commit
|
||
|
|
identification. If a single notify object is used, the preceding program can
|
||
|
|
describe the data structure within the program rather than externally. For
|
||
|
|
example:</p>
|
||
|
|
<pre> 1 10 USER
|
||
|
|
11 20 PGMNAM
|
||
|
|
21 23 PRODCT
|
||
|
|
24 29 LOCATN
|
||
|
|
30 49 DESC
|
||
|
|
50 51 0 QTY
|
||
|
|
52 220 DUMMY</pre>
|
||
|
|
<p>In each program that uses this notify object, the information specified
|
||
|
|
for the commit identification is unique to the program (the user and program
|
||
|
|
names are not unique). The notify object must be large enough to contain the
|
||
|
|
maximum information that any program can place in the commit identification.</p>
