5.1 Basic elements of job definition scripts

This section explains the basic elements of job definition scripts.

Important note

Note the following about coding job definition scripts:

• A line of a job definition script cannot exceed 8,191 bytes. If a line's length exceeds 8,191 bytes, the job definition script terminates with an error. A continuation line is treated as a separate line for purposes of line length. For details about continuation lines, see 5.1.6(3) Line continuation.

• For a line using an extended script command, the maximum length including the continuation lines is 8,191 bytes according to the limitations for extended script commands. For details about the limitations of extended script commands, see 9.1.3(1) Limitations.

• If a file path is converted during a file input or output operation, the number of bytes changes depending on the timing of the file input or output operation. In such a case, even if the maximum length of a line is exceeded due to conversion, processing continues and no error occurs.
