Hi, I have two related issues I'd like comments on.
Issue 1 - Global Values Some years ago, I had a situation where (a) I could supply low-level functions that carry out tasks, (b) I needed those functions to communicate with each other, but (c) I had no access to the module that invoked my functions. In order to achieve this, I hit on the idea that I also supply a module that I describe as a "global values" module. This module … (i) … defines the values that the functions use to communicate with each other; (ii) … is the subject of an import statement in each of my functions; (iii) … initialises its values at the start of each run (since the import only carries out an actual import once per session); (iv) … acts as a repository for the values thereafter. This solution works well. Given that I am not particularly concerned about efficiency, (1) Is this a reasonable way to achieve this goal? (2) Do you know of any better ways? Issue 2 - Passed Parameters I am now facing another situation where I am wanting to pass 6 or 7 parameters down through several layers of logic (function A calling function B calling ... ) and for results to be passed back. Having had the idea described above, I am considering using it again to save all the parameter-and-results passing. I see nothing wrong with doing that, but I may well be missing something!
