To contract on Glenn's thoughts ;\)
 Code:
$strLine = ReadLine(1)
While Not $Tag And Not @ERROR
	$Tag=InStr($strLine, 'Skipped with error')
	$strLine = ReadLine(1)
Loop
$=Close(1)
If $Tag  ; string was found!
    ; use Blat to send a "skipped found" email
Else
    ; use Blat to send an "skipped not found" email
EndIf


Gotta save those CPU cycles.
