Updating a Delta Comment: sccs cdc

If you forget to include something important in a comment, you can add the missing information using:

sccs cdc -r sid

The delta must be the most recent (or the most recent in its branch, see "Branches "). Also, you must either be the user who checked the delta in, or you must own and have permission to write on both the history file and the SCCS subdirectory. When you use cdc, SCCS prompts for your comments and inserts the new comment you supply:

$ sccs cdc -r1.2 program.c
comments? also taught get_in() to handle control chars

The new commentary, as displayed by prt, looks like this:

$ sccs prt program.c
