I'm looking for a tool to producing a cross-reference of where, in a set of Ada units, objects declared in package specifications or bodies (aka variables) are referenced (assigned or read). Does anyone know where such a tool is available? Alternative the location of a similar tool that I could modify to this purpose. Thanks, Rush Kester P.S. I know that global variables are "poor style." I didn't write the code, I'm just trying to understand it!
