RE: Initialisation of global variables between calls

[David FOXWELL <David.FOXWELL@xxxxxxxxx>]

I admit I am probably using too many global variables. I work in an environment where the norm seems to be copy and paste code rather than reuse it. If I were to pass parameters instead, the procedures would remain internal to that module so I'd then probably get my backside kicked for taking too long setting up prototypes and the rest for subprocedures that will never be reused. Most of my subprocedures just seem to be there make the code readable and avoid coding monoliths.

I'd really like to see an example of a program that doesn't use global variables.
