Maybe "pure" Fortran is unambiguous, but the attempts to enrich the syntax have introduced some real ambiguities. Will someone please say what the one true parse of statement "1" (line 3) is in the following example? dimension a(5) integer x7h 1 format(x7h)=a(x7h) 2 format(x7h(=a)x7h) 3 format(i) a(2) = 5 i = format(2) write (6,2) write (6,3) i end While the UNIX F77 compiler parses both statements "1" and "2", it is unable to classify 4 format(x7h)=a)x7h) even though all three statements can be parsed as formats. This problem goes away if you exclude the archaic counted Hollerith fields or require commas to separate conversion descriptors. -- Griff Smith AT&T Bell Laboratories, Murray Hill Phone: (201) 582-7736 Internet: ggs@ulysses.uucp UUCP: ulysses!ggs
