Debug in Compaq Visual Fortran ver. 6.6

Should post in Tek-Tips. They're more geared for this type of question

A good group for Fortran is:

You could also try

Hi
I assume you are debugging a *.exe?
If so then you should look at the messages returned in the command line window.

On the first line you will see the reference to the cause of the problem ...
examples : division by zero ...
: square root of negative number....
: etc, etc
There will also be an error code reference number. Look this up in the Compaq Help File. It may give you a clue.

Underneath the error notification you will find a list of the last run subroutines. At least you can find the routine in which the error occured, although the instigating cause may be in preceding routines.

Of course if your program is one long listing, and not split into discrete routines or functions, this may not be of much help.

You could also scroll through the assembler listing and you may find in bold type the last run code line of your program

Either way now begins the painful task of finding that error, step, by step, by step through the program ;>)
