<br>
<b>function</b> FindKey(const KeyValues: <b>array of const</b>): Boolean;
<br>

<br>
<b>Description</b>
<br>
Call FindKey to search for a specific record in a dataset. KeyValues contains a comma-delimited array of field values, called a key. Each value in the key can be a literal, a variable, a null, or nil. If the number of values passed in KeyValues is less than the number of columns in the index used for the search, the missing values are assumed to be null. 
<br>

<br>
The key must always be an index, which can be specified in the IndexName property. If IndexName is empty, FindKey raises an exception.
<br>

<br>
If the search is successful, FindKey positions the cursor on the matching record and returns True. Otherwise the cursor is not moved, and FindKey returns False.
