Operation numbers

Give each operation in an application a number in the range 1 to 255. Consider reserving number ranges for specific types of operations. For example, job setup operations could be from 1 to 9, computer processing operations from 10 to 240, and print operations from 241 to 255. When specifying operation numbers within these ranges, leave gaps for growth. For example, the first operation could be 05, the second operation 15, and so on.
