Interacting with other processes

[Gregory Daniel Denehy]

Hi,

I'm currently working on a graphical debugger for mercury using the existing 
debugger.  I am writing this in mercury using the tcl/tk interface.  The problem 
I am faced with is that I can't find a means to call the debugger from within my 
program that uses mercury input/output streams to communicate with the debugger. 
I am aware that it may be possible to implement this using tcl, but I want to 
avoid this if at all possible.  Can this be done?
