Re: Number of decimals

I forgot to mention that I placed another copy of the eval.zip file in the Temp directory. In this case I named it eval1.1.001.zip.
I have also now tested a syntax error on the dbl command and the result is "@" as I expected.

Thanks
Mike

The answer supplied when there was a syntax error was "0".  I thought that in these cases it would be better to give a response that was clearly not a legitimate answer to any calculation and change the response to "@" in the event of a syntax error.

Although I did say that C compilers give me trouble I can usually manage if I have a start like you've given me as well as the actual compiler that was used to compile the original.
