0001 * This file is an example to test the syntax highlighting file fortran-fixed.xml
0002 * (for fortran, fixed format)

0004 c <-- this is a comment in the old fortran 77 style (fixed form)
0005 c In the free form file, so we shouldn't use this kind of comments!
0006 c But fortran 90 still understands fixed form, when parsing sources with
0007 c the *.f extension.
0008
0009 * this 'c' shouldn't be highlighted as a comment!
0010  c

0012 *     Prints the values of e ** (j * i * pi / 4) for i = 0, 1, 2, ..., 7
0013 *         where j is the imaginary number sqrt(-1)
