[PCB_FORUM] help needed (skill routine to swap pins by selecting nets)

Hello all.
 
I first posted on CDNusers.org skill forum but it is not so efficient than this 
list ;-)
the link on cdnusers.org (with pictures to try to explain better...):
http://www.cdnusers.org/Forums/tabid/52/forumid/77/postid/1709/view/topic/Default.aspx
 
The routine works:
but some strange things appears:
after using this "swapn" command, all Allegro's command have to be "DONEd" to 
be able to call another one.
(it seems that the routine use (and set) some Allegro variable/setup...
Sometimes the routines loops and I have to kill the Allegro process.
The stop command puts all variables to "nil" but if I go in skill mode, some 
are not set to nil...
Stop Commands does not stop the "while comp=nil" loop....
 
Some  improvements can be applied:
the swap pins command fails if a bottom capacitor pin is close to the swapped 
BGA's pin (can be avoid by removing the display of opposite side of the BGA)
I will probably add a oops (a simple swap pins pin2 pin1 to remove the previous 
swap pins pin1 pin2.... and also a pins swaps record file (to be able to redo 
the whole swapping...)
 
So any help to improve it would be appreciate .
Thanks in advance.
 
    William.
