ùISO8859-1\@K¡éCannot use the comb command while there is an outstanding delta to the file. Use the delta command or the unget command; then use the comb command. A p-file exists which shows that someone is in the process of making a delta on the specified SCCS file. The comb command may only be used when no one else is modifying the specified SCCS file. The -p flag and the -c flag are mutually exclusive. The -p flag specifies the SID of the oldest delta for the resulting procedure to preserve. All older deltas are combined in the reconstructed file. The -c flag specifies a list of deltas (SIDs) that the shell procedure will preserve. The procedure combines all other deltas. The flags specified on the command line would create no changes to the SCCS file. The comb command as specified cannot do anything to the specified SCCS file.
