I use goto a lot with labels. For example, today I wanted to run some code before the main stuff but I only wanted to do it once but I didn't want to remove it. So, Goto Skip Code2RunOnce Skip: Code here to always run To run it once, I comment out the goto skip and then once it has run, I uncomment it so it skips over the Code2RunOnce. Now the purists amongst you will grimace and come up with all sorts of alternatives, but for me it is easy peasy. It works and it retains visibility of what I have done. If I need to run it again, a simple removal of a single quote and it is back in action. POWER TO ALL THE PEOPLE - RESISTANCE TO PURISTS IS NOT FUTILE.

Ummmmmm, that's not true, you can move forward with a Goto. A Do Loop IS always moving backwards. With a goto, you can skip code, or go back. And you can just as easily end up in a Do (or any loop, for next, while wend) loop 'forever'.

Hi Drew and John The mistake by John here is that the Exit Loop and Exit For represent only a very restricted GoTo as they only can exit to one specific point: the end of the loop. That makes them very predictable. Still, I often refrain from these and add a flag to raise or some other condition to check to stop the loop. The really ugly thing with GoTo is that is allows you to move backwards in the code to run it over again - do I need to remind about being caught in an endless loop caused by GoTo and some condition behaving otherwise than intended? I do, from my time with Algol where the compiler running on the IBM360 stopped those loops routinely (as we were only students at the technical university). A nightmare there is no reason to promote if you ask me. /gustav >>> DWUTKA at marlow.com 24-06-2009 23:58 >>> Yep. Wait a sec...are you and I in agreement? Charlotte, just admit defeat!!! If JC and I agree on something, it HAS to be true! ;) Drew -----Original Message----- From: accessd-bounces at databaseadvisors.com [mailto:accessd-bounces at databaseadvisors.com] On Behalf Of jwcolby Sent: Wednesday, June 24, 2009 2:24 PM To: Access Developers discussion and problem solving Subject: Re: [AccessD] Learning .Net -- PHP Instead? And for that matter, what is an Exit Do? It is a GoTo the line after the loop. It may not be called that but that is exactly what it is. John W.
