An existing external procedure does a load of calculations and then displays a subfile for a client.
I now need to be able to display it differently, ie in a visualization mode instead of modification mode so that function keys cannot be used and fields can be protected.
Normally, we would just add a parameter for the display mode and modify all callers, etc,etc.
What is an efficient way to modify this procédure? I am tempted to put a global field <mode> and add a procedure to set this mode from my caller before calling the subfile procedure. This way I will not touch the callers.
Any advice?
Thanks
