Rules for parsing

The content and format of the altered control statement to be parsed must correspond to valid DFSORT values as described in Using DFSORT program control statements, except when using the FIELDS operand with SORT or MERGE, or the COND operand with INCLUDE or OMIT (see EFS formats for SORT, MERGE, INCLUDE, and OMIT control statements).

You must observe the following rules for control statements to be returned to DFSORT for parsing:

The operation definer and corresponding operands must be in uppercase EBCDIC format.
At least one blank must follow the operation definer (SORT, MERGE, RECORD, and so on). A control statement can start with one or more blanks and can end with one or more blanks. No other blanks are allowed unless the blanks are part of a constant.
Labels are not allowed; a leading blank, or blanks, before the control statement name is optional.
No continuation character is allowed.
Comment statements, blank statements, and remarks are not allowed.

The content and format of the altered EXEC PARM option to be parsed must correspond to valid DFSORT values as described in Specifying EXEC/DFSPARM PARM options.

The following operands will be ignored by DFSORT if returned by an EFS program on the OPTION control statement:

EFS
LIST
NOLIST
LISTX
NOLISTX
LOCALE
MSGDDN
MSGDD
MSGPRT
SMF
SORTDD
SORTIN
SORTOUT
USEWKDD

The following EXEC PARM options will be ignored by DFSORT if returned by an EFS program:

EFS
LIST
NOLIST
LISTX
NOLISTX
LOCALE
MSGDDN
MSGDD
MSGPRT
