X 1.1.3.7 SORT-CONTROL

X The SORT-CONTROL special register is the name of an alphanumeric data
X item.

X >_Workstation_> Under AIX, OS/2, and Windows, it is implicitly defined as:


 X   01 SORT-CONTROL GLOBAL PICTURE X(160) VALUE "file name".

X Where "file name" is the file name used by SMARTSort as the source for
X additional sort/merge options. <_Workstation_<

X >_Host_> Under OS/390 and VM it is implicitly defined as:


 X   01    SORT-CONTROL GLOBAL PICTURE X(8) USAGE DISPLAY VALUE "IGZSRTCD"

X This register contains the ddname of the data set that holds the control
X statements used to improve the performance of a sorting or merging
X operation.

X Under OS/390, you can provide a DD statement for the data set identified
X by the SORT-CONTROL special register, and COBOL for OS/390 & VM will
X attempt to open the data set at execution time. Any error will be
X diagnosed with an informational message. <_Host_<

X You can specify the SORT-CONTROL special register in a function wherever
X an alphanumeric argument is allowed.

X The SORT-CONTROL special register is not necessary for a successful
X sorting or merging operation.

X Note that the sort control file takes precedence over the SORT special
X registers.

X When used in nested programs, this special register is implicitly defined
X in the outermost program.

X For further information, see the IBM COBOL Programming Guide for your
X platform.
