Title: Formatting in Fortran - Code::Blocks
Post by: chaitu49 on April 07, 2016, 10:46:23 pm

I am trying to convert an old code into GFortran using code blocks. I am running into a formatting issue. I would be grateful if anyone can help...

I have the following code:

implicit double precision (a-h,o-z)
         n = 7
         ns = 2

        dim = 2*n+3+ns

         write(*,21) !a bunch of variables to write !

 21    format(dim(e14.9e3))

I have the following errors:
"Positive width required in format specifier D"
"Format label 21 not defined"

Thanks in advance!

1) Hi and welcome to the forum
2) Use code tags if you post code or build logs (Use the # symbol in the new topic editor)
3) This is a forum about codeblocks the ide and not fortran the compiler, so you are here in the wrong place to ask this king of questions: http://forums.codeblocks.org/index.php/topic,9996.0.html
and: http://wiki.codeblocks.org/index.php/FAQ-General#Q:_What_Code::Blocks_is_not.3F
4) I have no idea about fortran code but i think this can help you:
