 Hi --
     I'm certainly happy to see someone with an interest in this.  First 
 of all ddd is working sort of.  If I move the mouse pointer too much in 
 the source window it crashes and this is easy to make happen.   But if I 
 don't move the mouse too much I can still get useful work done.
 
 The gdb problem is that I simply don't seem to have any way to print 
 dummy arrays in Fortran.  Thus if an array X() is passed into a 
 subroutine and I want to print locations X(3:7) there seems no way to do 
 this without going up a level and doing
 
 p x(3)@5
 
 Things are even worse for printing an arbitrary region of a two 
 dimensional array.
 I'm frequently in a position where I want to display small parts of very 
 large arrays.  If I could do this in gdb, I think there is a reasonable 
 chance I could figure out how to accomplish the same thing in ddd.
 
 Let me know if you would like more input from me.
 
 Many thanks,
     Fred
