- cdc - change the delta commentary of an SCCS delta

- _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

-
-
- 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

- 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.
