When debugging code how do I display the line number on which an error occurs?
I have worked with SUN FORTRAN under UNIX and it automatically spits out the line number, but CVF just provides an error message, making it difficult to debug.
You need to upgrade to 6.0 or later (6.5 is current), which has that feature. You can get the line number in a traceback message or the debugger will stop at the point of error.
However, also look at the 5.0D release notes for a technique to get the debugger to stop on some kinds of I/O errors.
