As much as I'd like to, I cannot agree: "The only embedded blanks permitted within a complex constant are between the separator and the end of a record and one blank at the beginning of the next record." An "embedded blank within a complex constant" is any blank which neither leads the complex constant nor trails it; in other words, any space between the left and the right parenthesis. It is not permitted, except around record breaks. If it is important, we can still ensure the tabular alignment of complex fields by right-flushing them in a field of width 2*w+3, where w is the width for a real constant.
