Points taken John, but if I do all the coding then I will not find any errors I
think.
I'll know soon whether my design is correct - it's really a question of using
correct Nyquist adjusted frequencies etc.

A third party DFT implementation should prove that the coefficients aren't
completely incorrect. Beyond that, wouldn't it be more useful to feed the
filter design parameters into another implementation of the Remez exchange
algorithm and compare the results?

Hi,
This is not a problem, but I would like to feed my data into a 3-rd party
program to prove my design, that's all :-)

Since the filter coefficients are the impulse response, you should be
able to do a DFT of the coefficients to get the frequency response.
