Searching the Help
To search for information in the Help, type a word or phrase in the Search box. When you enter a group of words, OR is inferred. You can use Boolean operators to refine your search.
Results returned are case insensitive. However, results ranking takes case into account and assigns higher scores to case matches. Therefore, a search for "cats" followed by a search for "Cats" would return the same number of Help topics, but the order in which the topics are listed would be different.
Words and Phrases
| Search for | Example | Results |
|---|---|---|
| A single word | cat
|
Topics that contain the word "cat". You will also find its grammatical variations, such as "cats". |
|
A phrase. You can specify that the search results contain a specific phrase. |
"cat food" (quotation marks) |
Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase. |
Using Boolean Operators
| Search for | Operator | Example |
|---|---|---|
|
Two or more words in the same topic |
|
|
| Either word in a topic |
|
|
| Topics that do not contain a specific word or phrase |
|
|
| Topics that contain one string and do not contain another | ^ (caret) |
cat ^ mouse
|
| A combination of search types | ( ) parentheses |

Variable pools
Variable pools are functional groupings of variables within Service Manager. There are currently four variable pools:
-
Global
A global variable is visible to the entire system. It begins with
$G.or$lo.. -
Local
A local variable is only visible to the RAD application in which it was defined. It begins with
$L.. -
Parameter
A parameter variable is defined on a parameter command panel. It may contain a value passed in from another application. By convention, parameter variables are written in uppercase letters, such as
$PHASEor$GROUP.LIST. Parameter variables are invisible to the debugger. -
Thread
A thread variable is only visible to the thread in which it was defined. The same variable in different threads has different values, even when the threads are spawned by the same parent.
| Variable pool | Variable | Comments |
|---|---|---|
| Global | $G. | |
| Global | $lo. | |
| Global | $MARQUEE. | |
| Global | $SYSPUB. | |
| Local | $L. | There is only one local variable. It can contain many pieces of data, similar to the way a structure contains many pieces of information. For example, $L.env and $L.file are two pieces of data that $L. can contain. |
| Parameter |
$PHASE $GROUP.LIST |
These are just a few examples, there are many parameter variables. |
| Thread |
$file $array $post |
These are just a few examples, there are many thread variables. |
