WRITE
WRITE DDCONCAT is a CLIST which allows the user to dynamically change the
WRITE concatenation sequence of any of the following DDs during logon or while
WRITE out of ISPF.
WRITE
WRITE SYSHELP
WRITE SYSEXEC

WRITE ISPPLIB
WRITE ISPMLIB
WRITE ISPSLIB
WRITE ISPTLIB
WRITE ISPLLIB
WRITE
WRITE It allows you to put one or more libraries before and/or after
WRITE each one of these standard dd's.
WRITE
WRITE Note: you are responsible for whether any specific library can, in
WRITE fact, be successfully concatenated to a given dd based on MVS
WRITE restrictions on dataset concatenations and installation-specific
WRITE restrictions. For example, Fidelity CLIST files are all defined
WRITE VB 255. An FB 80 library ahead of this concatenation will cause
WRITE any CLISTs executed in concatenation after the FB 80 library to
WRITE ABEND. Also, some installation-specific ISPF commands can only be
WRITE implemented by placing them in the first ISPTLIB library. If you
WRITE place a different ISPTLIB library first, you may, in fact, nullify
WRITE your ability to use these commands.
WRITE
WRITE DDCONCAT has 2 keyword parameters for each ISPF ddname and for
WRITE SYSPROC. The names of these keywords are the ddname prefixed by
WRITE an "A" or a "B". For example, the CLIST dd "SYSPROC" has the
WRITE keywords "ASYSPROC" and "BSYSPROC" associated with it; the panel
WRITE dd "ISPPLIB" has "AISPPLIB" and "BISPPLIB", etc. The "A" means
WRITE "after" and the "B" means "before".
WRITE
WRITE Consequently, you put the library names which you want to place
WRITE before the current xxxxxxx concatenation in the Bxxxxxxx keyword.
WRITE To place CLIST library "ABC.DEF.CLIST" ahead of the concatenation
WRITE in SYSPROC, you would invoke DDCONCAT as follows:
WRITE
WRITE %DDCONCAT BSYSPROC('''ABC.DEF.CLIST''')
WRITE
WRITE You may specify any or all of the keywords which DDCONCAT has in a
WRITE single call to DDCONCAT (indeed, you SHOULD do this for
WRITE efficiency's sake).
WRITE
WRITE DDCONCAT uses standard TSO dataset name qualification. This means
WRITE that if you specify a dataset name in single quotes, it will be
WRITE used as specified. If you do not specify the single quotes, your
WRITE user id will be prefixed in front of the dataset name. In the
WRITE above example, if you had specified BSYSPROC(ABC.DEF.CLIST), the
WRITE actual dataset to be used would have been &SYSUID..ABC.DEF.CLIST.
WRITE If you want to specify more than one dataset in a given keyword
WRITE parameter, the entire keyword value must be in single quotes as
WRITE well.
WRITE
WRITE Note that the use of single quotes in CLIST processing of a
WRITE KEYWORD parameter (such as BSYSPROC, or AISPPLIB in this example)
WRITE is not intuitively obvious. CLISTs interpret single quotes a
WRITE little strangely when passed as part of parameters. In the above
WRITE example, to maintain the single quotes around ABC.DEF.CLIST, three
WRITE single quotes on each side were needed. The outer-most single
WRITE quote encompasses the entire parameter, and the next two are then
WRITE interpreted as one single quote. Note how they are used in the
WRITE next example.
WRITE
WRITE For instance, if you wanted to place &SYSUID..GHI.JKL.ISPPLIB and
WRITE MNO.PQR.ISPPLIB after the ISPPLIB concatenation, you would specify
WRITE the command as follows:
WRITE
WRITE %DDCONCAT AISPPLIB('GHI.JKL.ISPPLIB ''MNO.PQR.ISPPLIB''')
WRITE
WRITE So, if you wanted to place all of your personal CLIST and ISPF
WRITE libraries in the proper concatenations while logging on, you could
WRITE call DDCONCAT in the following manner:
WRITE
WRITE %DDCONCAT BSYSPROC(PDS.CLIST) BISPPLIB(PDS.ISPPLIB) &STR(&PLUS)
WRITE BISPTLIB(PDS.ISPTLIB) BISPMLIB(PDS.ISPMLIB) &STR(&PLUS)
WRITE BISPSLIB(PDS.ISPSLIB) BISPLLIB(PDS.ISPLLIB)
WRITE
WRITE *** END OF HELP *** NO PROCESSING PERFORMED ***

Documentation
DDCONCAT is a CLIST which allows the user to dynamically change the
concatenation sequence of any of the following DDs during logon or while out of
ISPF (i.e. they must be done at the "READY" prompt of native TSO).
SYSHELP
SYSEXEC
SYSPROC
ISPPLIB
ISPMLIB
ISPSLIB
ISPTLIB
ISPLLIB
It allows you to put one or more libraries before and/or after each one of
these standard dd's.
Note: you are responsible for whether any specific library can, in fact, be
successfully concatenated to a given dd based on MVS restrictions on dataset
concatenations and installation-specific restrictions. For example, Fidelity
CLIST files are all defined VB 255. An FB 80 library ahead of this
concatenation will cause any CLISTs executed in concatenation after the FB 80
library to ABEND. Also, some installation-specific ISPF commands can only be
implemented by placing them in the first ISPTLIB library. If you place a
different ISPTLIB library first, you may, in fact, nullify your ability to use
these commands.
DDCONCAT has 2 keyword parameters for each ISPF ddname and for SYSPROC. The
names of these keywords are the ddname prefixed by an "A" or a "B". For
example, the CLIST dd "SYSPROC" has the keywords "ASYSPROC" and "BSYSPROC"
associated with it; the panel dd "ISPPLIB" has "AISPPLIB" and "BISPPLIB", etc.
The "A" means "after" and the "B" means "before".
Consequently, you put the library names which you want to place before the
current xxxxxxx concatenation in the Bxxxxxxx keyword. To place CLIST library
"ABC.DEF.CLIST" ahead of the concatenation in SYSPROC, you would invoke
DDCONCAT as follows:
%DDCONCAT BSYSPROC('''ABC.DEF.CLIST''')
You may specify any or all of the keywords which DDCONCAT has in a single call
to DDCONCAT (indeed, you SHOULD do this for efficiency's sake).
DDCONCAT uses standard TSO dataset name qualification. This means that if you
specify a dataset name in single quotes, it will be used as specified. If you
do not specify the single quotes, your user id will be prefixed in front of the
dataset name. In the above example, if you had specified
BSYSPROC(ABC.DEF.CLIST), the actual dataset to be used would have been
&SYSUID..ABC.DEF.CLIST. If you want to specify more than one dataset in a
given keyword parameter, the entire keyword value must be in single quotes as
well.
Note that the use of single quotes in CLIST processing of a KEYWORD parameter
(such as BSYSPROC, or AISPPLIB in this example) is not intuitively obvious.
CLISTs interpret single quotes a little strangely when passed as part of
parameters. In the above example, to maintain the single quotes around
ABC.DEF.CLIST, three single quotes on each side were needed. The outer-most
single quote encompasses the entire parameter, and the next two are then
interpreted as one single quote. Note how they are used in the next example.
For instance, if you wanted to place &SYSUID..GHI.JKL.ISPPLIB and
MNO.PQR.ISPPLIB after the ISPPLIB concatenation, you would specify the command
as follows:
%DDCONCAT AISPPLIB('GHI.JKL.ISPPLIB ''MNO.PQR.ISPPLIB''')
So, if you wanted to place all of your personal CLIST and ISPF libraries in the
proper concatenations while logging on, you could call DDCONCAT in the
following manner:
%DDCONCAT BSYSPROC(PDS.CLIST) BISPPLIB(PDS.ISPPLIB) &STR(&PLUS)
BISPTLIB(PDS.ISPTLIB) BISPMLIB(PDS.ISPMLIB) &STR(&PLUS)
BISPSLIB(PDS.ISPSLIB) BISPLLIB(PDS.ISPLLIB)
