[comp.lang.fortran] Comments and Continuation

mjs@hubcap.clemson.edu (M. J. Saltzman) (02/23/91)

Does the fortran 77 standard disallow comments interspersed with
continuation lines?  For example

	integer   	i,j,
c this comment splits the statement it appears inside of
     1                  k,l,m,n


The Ultrix(tm) f77 compiler objects to the improperly-terminated first
line, and the illegal continuation character on the second line.
Is this a bug or a feature?

(No, it's not my own code, thank you.)

E-mail responses are fine.  Thanks in advance.

The full Fortran 77 language explicitly allows comment lines between
the initial and first continuation lines of a statement, or between
continuation lines; the subset language explicitly prohibits such
comment lines.  The relevant section of the standard (X3.9-1978) is
3.2.1, page 3-2 and 3-2s, lines 36-40.
