I'm not sure this represents a 'yay' or a 'nay' :) Problems with standards: one man's meat is another man's poison (or as said by an extremely talented singer-songwriter who is nonetheless unknown: "One man's verse is another man's prose"). What is descriptive to some might not be for others. ALL CAPS is historical I think (MBASIC anyone? Further back?) Since I agree with the basic premise, I've coded my stuff to conform to what came before me (my consultant background showing). That way, it's at least uniform. One thing I do strongly agree with is the labelling of global variables. However, in this language EVERY variable is global :( What I've done is to indicate where a variable is tweaked elsewhere (as in a GOSUB) within the comments.
