Matching the Beginning of a Line A caret (^) instructs QuickTest to match the expression only at the start of a line, or after a newline character.
For example:
book
matches book within the lines—book, my book, and book list, while
^book
matches book only in the lines—book and book list.

Remarks
The actual pattern for the regular expression search is set using the Pattern property of the RegExp object.
The Execute method returns a Matches collection containing a Match object for each match found in string. Execute returns an empty Matches collection if no match is found.
The following code illustrates the use of the Execute method.
Function RegExpTest(patrn, strng)
Dim regEx, Match, Matches ' Create variable.
Set regEx = New RegExp ' Create a regular expression.
regEx.Pattern = patrn ' Set pattern.
regEx.IgnoreCase = True ' Set case insensitivity.
regEx.Global = True ' Set global applicability.
Set Matches = regEx.Execute(strng) ' Execute search.
For Each Match in Matches ' Iterate Matches collection.
RetStr = RetStr & "Match found at position "
RetStr = RetStr & Match.FirstIndex & ". Match Value is '"
RetStr = RetStr & Match.Value & "'." & vbCRLF
Next
RegExpTest = RetStr
End Function
MsgBox(RegExpTest("is.", "IS1 is2 IS3 is4"))
