cdc - change the delta commentary of an SCCS delta
SSSSYYYYNNNNOOOOPPPPSSSSIIIISSSS
ccccddddcccc ----rrrrSID [----mmmm[mrlist]] [----yyyy[comment]] files
DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
_c_d_c changes the _d_e_l_t_a _c_o_m_m_e_n_t_a_r_y, for the SID (SSSSCCS IIIIDDDDentification
string) specified by the ----rrrr keyletter, of each named SCCS file.
_D_e_l_t_a _c_o_m_m_e_n_t_a_r_y is defined to be the Modification Request (MR) and
comment information normally specified via the _d_e_l_t_a(1) command (----mmmm and
----yyyy keyletters).
If a directory is named, _c_d_c behaves as though each file in the directory
were specified as a named file, except that non-SCCS files (last
component of the pathname does not begin with ssss....) and unreadable files
are silently ignored. If a name of ---- is given, the standard input is
read (see _W_A_R_N_I_N_G_S) and each line of the standard input is taken to be
the name of an SCCS file to be processed.
Arguments to _c_d_c, which may appear in any order, consist of _k_e_y_l_e_t_t_e_r
arguments and filenames.
All the described _k_e_y_l_e_t_t_e_r arguments apply independently to each named
file:
----rrrr_S_I_D Used to specify the _SCCS _I_Dentification (SID) string
of a delta for which the delta commentary is to be
changed.
----mmmm_m_r_l_i_s_t If the SCCS file has the vvvv flag set (see _a_d_m_i_n(1)]
then a list of MR numbers to be added and/or deleted
in the delta commentary of the SID specified by the
----rrrr keyletter _m_a_y be supplied. A null MR list has no
effect.
MMMMRRRR entries are added to the list of MRs in the same
manner as that of _d_e_l_t_a(1). In order to delete an
MR, precede the MR number with the character !!!! (see
_E_X_A_M_P_L_E_S). If the MR to be deleted is currently in
the list of MRs, it is removed and changed into a
``comment'' line. A list of all deleted MRs is
placed in the comment section of the delta commentary
and preceded by a comment line stating that they were
deleted.
If ----mmmm is not used and the standard input is a
terminal, the prompt MMMMRRRRssss???? is issued on the standard
output before the standard input is read; if the
standard input is not a terminal, no prompt is
issued. The MMMMRRRRssss???? prompt always precedes the
PPPPaaaaggggeeee 1111
ccccddddcccc((((1111)))) ccccddddcccc((((1111))))
ccccoooommmmmmmmeeeennnnttttssss???? prompt (see ----yyyy keyletter).
MMMMRRRRssss in a list are separated by blanks and/or tab
characters. An unescaped new-line character
terminates the MR list.
Note that if the vvvv flag has a value (see _a_d_m_i_n(1)),
it is taken to be the name of a program (or shell
procedure) which validates the correctness of the MR
numbers. If a non-zero exit status is returned from
the MR number validation program, _c_d_c terminates and
the delta commentary remains unchanged.
----yyyy[_c_o_m_m_e_n_t] Arbitrary text used to replace the _c_o_m_m_e_n_t(s) already
existing for the delta specified by the ----rrrr keyletter.
The previous comments are kept and preceded by a
comment line stating that they were changed. A null
_c_o_m_m_e_n_t has no effect.
If ----yyyy is not specified and the standard input is a
terminal, the prompt ccccoooommmmmmmmeeeennnnttttssss???? is issued on the
standard output before the standard input is read; if
the standard input is not a terminal, no prompt is
issued. An unescaped new-line character terminates
the _c_o_m_m_e_n_t text.
Simply stated, the keyletter arguments are either (1) if you made the
delta, you can change its delta commentary; or (2) if you own the file
and directory you can modify the delta commentary.

adds bl78-12345 and bl79-00001 to the MR list, removes bl77-54321 from
the MR list, and adds the comment ttttrrrroooouuuubbbblllleeee to delta 1....6 of s....file.

If SCCS filenames are supplied to the _c_d_c command via the standard input
(---- on the command line), then the ----mmmm and ----yyyy keyletters must also be used.
