In the Author's Edition and the Author's Help files there is a topic
HOW TO READ A SYNTAX DIAGRAM
I see some syntax diagrams that I can't understand using the above explanation.
So I seek enlightment.
CASE 1: According to HOW TO READ A SYNTAX DIAGRAM:
When you can select an item or take none, the choices are stacked below the
main path.
>>——COMMAND——+——————————+——————————————————————————————————————————————————><
+—argument—+
+—KEYWORD——+
A default is shown above the main path.
+—DEFault——+
>>——COMMAND——+——————————+——————————————————————————————————————————————————><
+—argument—+
+—KEYWORD——+
The following diagram shows a default value (COMMIT) but does not show
+——————————————————+ below the default to indicate item is optional
+———————————————————————————————————————————————————————————————————————————+
| |
| <—————————————————————+ |
| +—COMMIT————————————+| |
| >>——SQL———+—RELEASE———————————++——+—+ select-statement +——+————————————>< |
| +—NOCOMMIT——————————+ +—+ insert-statement +——+ |
| +—REPEATable————————+ +—+ connect-statement +—+ |
| +—INDicators————————+ +—EXECUTE——+————————+———+ |
| +—NOINDicators——————+ +—string—+ |
| | (1)| |
| +—PGMOWNER——word————+ |
| | (2)| |
| +—SUBSYSid——word————+ |
| | (2) | |
| +—PLAN——word————————+ |
The only difference I see is that SQL has a repeat arrow; but that should make
no difference
or if it does then shouldn't the HOW TO explain it?
CASE 2: Some diagrams include a character in the repeat arrow e.g.
<————,————————+
This is not explained in the HOW TO.
I may send some other cases later. Thanks for your attention.
