To remind me what I have done to an ASP file, I will add a comment block to the top of every file (after Option Explicit, of course). This comment block usually contains the following:
- Name of the file
- Basic description of what the file does
- Date created
- Modification log containing dates, initials, and descriptions of what has been done to the file
This helps me keep track of changes to the file. This is especially helpful for use with a source code control program like SourceSafe or PVCS.
