I've been at shops that assign labels win ascending order. A few months of maintenance and they're out of order. Even when they are in order they're harder to understand than mnemonic labels.

With names, you don't know where to look (up or down).

(Not > relevant to the numeric vs. alphanumeric choice) Rarely do I use FORMAT statements in any language. If I do use them, I put them adjacent to the statement that requires it. --- This email has been checked for viruses by Avast antivirus software. https://secure-web.cisco.com/11Vh_GdEyOK-9-BVnSSWh2X5qxoQIghI9q06_Z_Z3p1PwNMxK7FGYi_uaph1fIDbl2q5hs47x2xXSKvC3NAC5rxGeW_5ZJ1vDwOjBatrmWhYqjuUzxkB1bGKJPwW24f1j_n4LvjEiAobHlEORcVhzFVOHI342Kh3dZ0fRd82EZcP6T7ZReMu2C1N7r-ID_AwvmQgvqtQXlnfpTzeukrj43nZTOv2lsxdnZmKDIpnVvmVv4R0tPtFCa0Sxrk6lcfp2vXhea3QsZcE2fzNi4T761f1TReOjnG3aZL8WEOFxXu3Em7oKVao5iXW_ph6xvs19cTOkl1wx3T61TnsfzaK1fsJg2HMCE5J1oPj5Gt1kP5cSYBdWpyuPafUBBw07sh4Hsa2ItkDqloBU-ArnpLkN9ELw1RkRPLgqm4dfaFjXJ6AlJ3szxk7Qca74DWLP7xty/https%3A%2F%2Fwww.avast.com%2Fantivirus
