I disagree. The existence and intelligent use of labeled blocks of code (paragraphs and sections in COBOL, Procedures in PL/1, labels and sometimes separate CSECT/RSECT's in assembler) are what provide the tag to which you may direct a person or a computer's attention. The first thing I do these days when editing a program for maintenance is "UNNUM". I edit on TN3270E 50x132 almost all the time, and I find that the visual clutter of sequence numbers is far too visually confusing. > [1] That sort of thing can cause problems reconciling independent > changes when using something like cvs[2]. Again, I disagree. Labels and intelligent, maintainable code structure are what prevent such problems. > [2] Not a pharmacy. I think everyone here does (or should) already know that, but it was worth a small chuckle.
