ICPREF
The ICPREF keyword is optional on the GLBL, GROUP, IC, and AIC commands.
This keyword is available in ICPSYSIN; it is also available in global and database-specific options modules. The following table describes the keyword.
Output image copy data set name prefix keyword
To do this | Specify this in ICPSYSSIN |
|---|---|
Identify a data set name prefix for the output image copy data set. | ICPREF(dsnprefix) |
Internal default: None | |
A data set name prefix is required when you dynamically allocate an output image copy data set by using the ICALLOC(Y) and IC(*) keywords (as described in ICALLOC and IC). The prefix can be 1-33 characters. This prefix is the high-level qualifier of the data set name. The prefix can include periods and must conform to normal data set naming standards; it cannot end with a period.
For dynamic allocation, you must provide a data set name prefix or use a data set name user exit (ICP$DSN or RCU$DSN) that does not require a data set name prefix. For more information, see Using-the-image-copy-data-set-name-user-exit.
Do not specify prefixes SYS, PLUS, and DFS when using preallocated GDGs; the Image Copy function ignores ddnames with these prefixes.
