Ctl-d for sure.  Many many thanks.

That's what I always thought.  But these days Ctl-Delete just deletes a single line.  I have an output of several hundred lines. 

One more hearty thank you for the help with my question.  I have not seen the DataFrame command before but it does exactly as requested.  Many thanks ...............Edgar

Thanks to all for this amazing fast help.  I view a matrix as the multiplication table for a finite algebraic system.  If the entries are all integers, no problem at all.

1 2 3

3 2 1

2 2 2         The product (13)2 is A[A[1,3],2] = A[3,2]=2. 

No problem unless there are 0's in the matrix (and I would like the symbols to be other than integers). 

I've received some good suggestions.  Thanks again.

I am cursed with being a fussy guy, I guess.  The problem with the style=planar option is that you lose control over placement of vertices.  If you want to demonstrate the Dijkstra algorithm, for instance, with a shortest path from A to E, I would like A on the left and E on the right. 

And the reason I started this thread was that, in the absence of an option, Maple assigned positions to edge labels which I did not always like.  I agree, of course, that positioning by hand is a pain!  ................Edgar

display(p1, p2);

Further comment:  Interesting that I cannot label a vertex I since this has a special meaning, but I can use "I".  So must I not also use "A", "B", and so on.  Fun and games. Again, many thanks Carl for pointing me in the right direction.

Thanks very much for the help ..................Edgar

@acer 

You are keeping a close watch on me acer, and being a tremendous help!  Many many thanks.  I have completed the worksheet that has been giving me trouble and it is working beautifully.  Thanks again, Edgar

@acer 

Wonderful!  Thank you very much.  ............Edgar

I have been having the same problem the past couple of days, and the corrupted file is just a few lines of garbage.  Edgar

@tomleslie 

Perfect.  Thank you very much!  .............Edgar

@rlopez 

Every symbol in the matrix is surrounded by " " which I can't eliminate.  .............Edgar

@Daniel Skoog 

I was sure what I wanted had to have been done and probably within Maple somewhere.  I looked hard but never found it.  Thank you for the direction.  ..............Edgar

@Rouben Rostamian  

This is very impressive.  Thank you very much. 

Thanks for the help.  this is exactly my problem, penalized by Maple for getting a 64 bit machine.    So many of my programs won't run - or I can't get them to run - under regular Maple.  Why did Maple do this to us?  Is anybody from Maple listening?  ...........Edgar
