Thanks John. I tell people I can spell, I just can't type. Looks like I can't type numbers either :)

Still, Allen Fields's typo needs correction for the record. For old-style blocking the maximal BLKSIZE= value was 32760---not 32670. The rationale for it was that the integer quotient of [2^15 - 1 =] 32767/8 is 4095, and 4095 x 8 is 32760, which is the largest integer not greater than 32767 that is a multiple of eight (for doubleword alignment).
