Does anyone know if NAG has an e-mail address which accepts reports of suspected bugs? I find that calling one of their random number generator routines works fine if I request an even number of random numbers but blows up (produces Infinity - NaN) if an odd number of random numbers is requested. A sample program which does this is included below: implicit double precision(a-h,o-z) parameter(maxobs=365) double precision e(maxobs) external g05cbf, g05fdf call g05cbf(170565) do 100 n=1,2 call g05fdf(0.d0,1.d0,maxobs,e) do 101 i=1,maxobs write(8,*)i,e(i) 101 continue 100 continue stop end This will blow up with maxobs set to 365 or 367 or any other odd number I've tried > 100, but seems to work fine at 364 or 366 or any other even number > 100. Thanks in advance for any advice. Ken Vetzal (kvetzal@watarts.uwaterloo.ca)
