IGZ0027W The sort control file could not be opened.

Explanation
 An attempt to open the sort control file has failed.
Possible reasons for the open failure include:  A ddname for the sort control file was not provided.
The IGZSRTCD ddname was provided, but the file associated with
the ddname could not be found.

 When the sort control file cannot be opened, user-supplied
sort control cards will not be passed to Sort/Merge.
 The sort
control file is optional. On MVS™,
if you did not provide a ddname for the sort control file (the sort
control file name is IGZSRTCD unless it is overridden by changing
the value of the SORT-CONTROL special register) you will also get
this message: IEC130I 'IGZSRTCD DD STATEMENT MISSING'. This message
is informational only.

System action
 No system action was taken.

Programmer response
 If you want to pass in sort control cards
from the sort control file, verify that the ddname is specified and
the file is available.
