CVS                      Convert String to Single Precision

 y! = CVS(4-byte-string)

    Converts a four-byte string expression to a single-precision number.

   ----------------------------------------------------------------------

      Notes:    A single-precision real number must be converted to a
                string (via MKS$) before being stored in a random access
                file. To retrieve such a number, first assign it to a file
                buffer field (with GET), then use CVS.
