Controls Sort of records with duplicate keys: Whether original order is maintained. Defaults is to true

Parameters:

duplicatesInOrder -

addKeyAscending

public void addKeyAscending(ISMObject field)

addKeyAscending

public void addKeyAscending(String[] keyNames)

addKeyDescending

public void addKeyDescending(String[] keyNames)

addKeyAscending

public void addKeyAscending(ISMObject[] fields)

setEbcdicSort

public void setEbcdicSort(boolean newValue)

===== WARNING ====>: Please note, DO NOT use when sorting Numeric VALUES In ASCII character '1' is before 'A', in EBCDIC it is the other way ('A' before '1') Setting EBCDIC Sort will convert all the values to EBCDIC before comparison (Hence lower performance).

Parameters:

newValue -

sortArray

public void sortArray(AbstractCBLField arrayField)

sort

public int sort()

sort

public int sort(boolean onFailThrowException)

Returns:

int - 0 is success, 16 is failure designed to return a value indicating whether sort is successful or not. For documentation please see: http://publib.boulder.ibm.com/infocenter/iadthelp/v7r0/index.jsp?topic=/com.ibm.etools.iseries.langref.doc/c0925395446.htm It says: When used in nested programs, the SORT-RETURN special register is implicitly defined as GLOBAL in the outermost COBOL program. The SORT-RETURN special register contains a return code of 0 (successful) or 16 (unsuccessful) at the completion of a sort/merge operation. You can set the SORT-RETURN special register to 16 in an error declarative or input/output procedure to terminate a sort/merge operation before all records are processed. The operation is terminated before a record is RETURNed or RELEASEd. You may specify the SORT-RETURN special register in a function wherever an integer argument is allowed.
