Input to program changed so that test runs no longer require an eof; an 'n' or 'N' now terminates input.

Input/output not controlled by port library.

Date and time routines have been removed and/or replaced by the standard CALGO library routines. The case changer has also been disabled -- all input should be in upper case.

Function 10 is not recognised as executing successfully in single precision although the results are similar to the double precision version.

The original source had a very large number of variables that were set but never used or declared but never used. These should have been automatically removed.
