Understanding SJF terms
To use the SJF macros and services, you must understand several
terms. These terms are defined in this information. The statement
below illustrates some of the definitions that follow. The definitions
refer to specific portions of the statement.
STMNT OPTIONS(A,B,(c,d,e)) TYPE- operand
- A stand-alone word specified on a statement. It has no sub-values specified with it. In the statement example, TYPE is an operand.
- keyword operand
- A word specified on a statement that has a value or list of values (subparameter) specified with it. In the statement example, OPTIONS is a keyword operand.
- subparameter
- A value or list of values specified with a keyword operand. In the statement example, A and B and (c,d,e) are all subparameters.
- subparameter number
- The position of a subparameter within a keyword operand. In the statement example, A is subparameter number 1, (c,d,e) is subparameter number 3.
- sublist element number
- The position of a sublist element within a sublist. In the statement example, d is sublist element number 2.
- sublist
- A single subparameter that consists of a list of values. In the statement example, (c,d,e) is a sublist.
- sublist element
- One value within a sublist. In the statement example, c and d and e are each sublist elements.
- choice
- The data type of a predefined set of subparameters defined for
a keyword operand. Only one subparameter may be selected and specified.
In the following example, only one of the four choices in parentheses
may be specified.
DATACK(BLOCK|UNBLOCK|BLKCHAR|BLKPOS) - character
- The data type of a string of characters. Allowable characters and string length are defined for each keyword. For some keywords the string can be repeated, delineated by periods. Each delineated string is called a level. In the example DEST(POK.POST), POK and POST are levels.
- numeric
- The data type of a character representation of an integer, for example, 2 in COPIES(2).
- text unit
- Parameter information that represents a keyword operand and its subparameters. More than one text unit may be needed to represent an entire keyword operand. For more information about text units, see Dynamic output.
- text unit pointer list
- A contiguous list of 4-byte pointers. Each pointer points to a specific text unit. The last pointer in the list must have the left-most (high-order) bit set on.
- output descriptor
- An object that represents the output format characteristics of a SYSOUT data set.
- OUTDES statement
- An alternate form of OUTPUT JCL statements that is used in dynamic output environments. (See Understanding the OUTDES statement for the syntax and other information about OUTDES.)
- verb
- Identification information that appears in the SWBTU prefix.
