--- Comment #2 from urbanjost at comcast dot net --- Created attachment 54640 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54640&action=edit interactive program for trying out NAMELIST group input This may be an "oops" after all; looks like I have been depending on a non-standard behavior after reviewing your comment and trying to find in the standard what should happen. Ends up there is a statement that if the LHS describes a scalar value the RHS can only have one value that I had not noticed. After trying the attached interactive program with several compilers and reading the latest version of the Fortran standard, it appears to be an extension to follow x(2,3)= by more than one value, although so far NAG is the only one that warns or gives an error per the previous comment (I do not have access to nagfor(1) currently). The correct way to just fill in array order appears to be to use null values and have the LHS be the array name: x=9*,1,2,3 which would start filling on the tenth value regardless of the shape of x, apparently. For the case of a vector x(10:)=1,2,3 would also be defined by the standard. For multiple dimensions I guess you just have to figure out the number of null values to use instead of giving a starting "address". Thanks for the review, but although I have used this syntax for a very long time it is apparently (now?) an extension to allow it, so behavior can legitimately vary.
