memory_file_substring(+Handle, ?Before, ?Length, ?After, -SubString)

SubString is a substring of the memory file. There are Before characters in the memory file before SubString, SubString contains Length character and is followed by After characters in the memory file. The signature is the same as sub_string/5 and sub_atom/5, but currently at least two of the 3 position arguments must be specified. Future versions might implement the full functionality of sub_string/5.
