Why not simply adding an internal procedure where all global variables get
initialized (or reset)?
This procedure can be called by the main procedure (like any other
procedure).

Betreff: Initialisation of global variables between calls

Hi,

Just wondering what is a good/normal approach to this. Starting to use
linear main programs has made me stop and rethink.

Say I have a program that treats a client, ends, then treats another client.

Up until now, I've just relied on the program analysis to set the variables
at the right place. So at any given time, there could be global variables
containing information on the current client and others still containing
information on the previous client until they are used.

In a linear main program, wouldn't it be easiest to just initialise all
global variables in the main procedure? Would it work if they were all
declared as part of a data structure so that they could be reset by one
command?

I know, reducing the number of global variables would also help.
