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 |

Variables used in links
The variables used in links are listed below. The application "us.link" is in charge of executing the link expressions using the values set in those variables. If values for the logical variables are not specified, they default to false. Unless noted, the special variables used by prior applications are also used by us.link.
Variable | Value | Use |
---|---|---|
$fill.date.calendar | true or false | Enables a pop-up calendar window, and is used for date/time fields. Note: $fill.date.calendar is no longer needed when using 6.2 or later clients, which allow you to define a date/time field on a form as a "calendar"-type widget. |
$fill.display.add | true or false | Determines whether you can add a record if the current link query returns no records. |
$fill.display | true or false | Determines whether the record you are filling from opens before you copy data from it into your source record. |
$fill.exact | true or false | Forces the project panel to adhere strictly to data types and index levels during the project. |
$find.skip | true or false | Tells the application to skip the current entry whenever a "find" is performed on the field. |
$fill.list | An array list of values. For example: $fill.list={"a", "b", "c"} | Enables you to fill from an array list of values. Target file and field names are not required when using this option. For example, $fill.list={"a","b","c"} will execute a pop-up window where the user can select one of the array values, a, b, or c. |
$fill.recurse.msg | A message. For example: $fill.recurse.msg="Hello world" | Defines the message to appear on a recursive link (when $fill.recurse=true). |
$fill.option.copy | true or false | This option is no longer necessary when using us.link. |
$fill.option.skip | true or false | Enables the skip option to skip the current link entry and move on when displaying the results of a recursive fill. |
$fill.recurse | true or false | Determines whether to move to the next entry in the link record (perform a recursive fill). |
$fill.replace | true or false | Governs whether a field that contains data should be overwritten with new data (including NULL). Only used for the project portion of a fill, not fields specified on the fill to/fill from section of the link line. |
$fill.search.format | Form to use when performing a fill. For example: $fill.search.format="company" | Defines the search screen to use when performing a fill. If this variable is set in the link expression, and the field that you are filling is NULL, the indicated search screen opens. The search created here continues the standard fill process. |
$fill.skip | true or false | Tells the application to skip the current entry and continue based upon the value of $fill.recurse for that entry. |
$fill.structure | Specific link. For example: $fill.structure={1,"rad"} | Enables you to perform a find from a field that is part of a structured array and to use fill to move information into that specific element of the structured array when: - The field name to fill from/post to is part of the structured array. - The field name to fill from/post to is not used in any other structure of the database dictionary record. - The name of the structure must be the same as the name of the array of which it is a part. To use find/fill on a structured array, you must set up the variable $fill.structure in the expressions of the specific link line. $fill.structure is an array of two elements. The first is the index of the field (that is used as the source field) in the structure and is of type number. The second is the name of the structure and is of type character. When using the fill function on a structured array, you can only modify the specific line of the structure being accessed. Instead of the actual field name, use the index number of the field within the structure. This includes the source field. |
$project.first | true or false | Governs whether a project should be done before moving any of the fields defined in the list of fill to/fill from fields. |
$fill.mult | true or false | Determines whether or not you can fill information from multiple records. True enables fill information from multiple records. The default value is true. |
