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.
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. |
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 |

RAD function: denull
A RAD function that compresses an array by removing all trailing NULL entries and returns the compressed array.
Function
denull
Format
denull(array)
Factors
- If the array contains a NULL entry in the middle of the array, that entry is not removed.
-
Using denull on an empty array of structures converts the array of structures to a simple array.
Note Always test for NULL first.
-
Displaying arrays extends the length of the array to accommodate window size.
Tip It is a good practice to denull arrays before records are added or updated. You can use
denull(contents())
to accomplish this, but you should first ensure that the contents do not include any empty array of structures or they will be converted to simple arrays.
Example
denull({1,2,3,,})
Returns {1,2,3}
.
denull({1,,2,,})
Returns {1,,2}
.
