Notes:
1. In a TSO environment, it is normally possible for the terminal operator to
interrupt processing at any time by means of an ATTENTION interrupt. In
order to protect the integrity of the CSD file, DFHCSDUP does not respond to
such an interrupt until after it has completed the processing associated with
the current command. It then writes message number ‘DFH5618’ to the
put-message exit (see “The put-message exit” on page 759), where this is
available, and also to the default output file:
AN ATTENTION INTERRUPT WAS
REQUESTED DURING DFHCSDUP PROCESSING
Your put-message exit routine can terminate DFHCSDUP, if desired. (Note
that you must supply a put-message routine if you want your operators to
regain control after an ATTENTION interrupt.)
2. Suitably authorized TSO operators can use the CEDA INSTALL transaction to
install resources that have previously been defined with DFHCSDUP. For
information about the CEDA INSTALL command, see the
CICS Resource
Definition Guide
.
Entry parameters for DFHCSDUP
When invoking DFHCSDUP, your program passes a parameter list addressed by
register 1. It may pass up to five parameters, as described below:
OPTIONS
A list of character strings, separated by commas. (The information passed here
is that which would otherwise be passed on the PARM keyword of the EXEC
statement of JCL.) A maximum of four options can be specified:
CSD({READWRITE|READONLY})
specifies whether you require read-write or read-only access to the
CSD.
PAGESIZE(nnnn)
specifies the number of lines per page on output listings. Valid values
for nnnn are 4 through 9999. The default value is 60.
NOCOMPAT|COMPAT
specifies whether DFHCSDUP is to be invoked in compatibility mode.
By default, it is invoked in noncompatibility mode. For details of
compatibility mode, see the
CICS Resource Definition Guide
.
UPPERCASE
specifies that output listings are to be printed entirely in uppercase
characters. The default is to print in mixed case.
DDNAMES
A list of ddnames that, if specified, are substituted for those normally used by
DFHCSDUP.
HDING
The starting page number of any listing produced by DFHCSDUP. You can use
this parameter to ensure that subsequent invocations produce logically
numbered listings. If this parameter is not specified, the starting page number is
set to 1.
