Thanks to John, Drew and All For a long while now I have been reading the postings on the list about Global variables "bad practice", "avoid using them", etc. I have a couple of old programs that have been running cleanly for years and they use a large amount of global variables. Many of the variables are carried through various phases of the project and some are regularly being changed/refreshed. Yes and some are integers. After reading "bad practice" I got worried that I was doing something majorily wrong. I sat down and tried to figure out how I would carry some of these variables forward. It amounted to a large increase in the code necessary to do this and in some cases it involved complex/messy error trapping vs simple declaring the variable and trapping for errors. Anyway after this discussion I am now aware of what is meant by and in what circumstances individuals deem it "bad practice" and that on the otherhand handled properly it is not necessarily a bad thing. Another thing to keep in the back of my mind when developing an application. Old dog new tricks.
