Read article by Erika in October 2006 Inside Sesame about Faster Forms with SBasic. I found it very informative and thought provoking. Thanks Erika for various tips. I have habit of leaving old codes within  /*          */.  Lots of earlier coding done with arrays and loops were replaced with new coding with @xlookupall( ), @xlookupSourceListAll( ) and stringarrays functions made available with later versions of Sesame.  My question is,  does such accumulation of older codes within comments in any way slow down the forms?  Do the comments go through compilation? Is there any case against such accumulation of codes other than cluttered look of programing module? If it does and I am better off removing them, if not then who knows, someday I might get some hint from them when I face some new challenges!
