Description
This command can be used to search within a text file for a specified string. It returns a Boolean value to indicate whether the search was successful or not.
It can be used for custom File I/O scripts.
This command can only be run on a file that is already open using fileOpen in Read mode. If the file has not been opened with readable flags then seekToString will fail.
