A batch job is an entity consisting of commands to the SINTRAN III system and possibly source input to subsystems or user programs called.
The first command in a batch job is always the @ENTER command, identifying the user. A batch job is terminated by two consecutive ESC characters (octal 33). These two characters correspond to the @[[LOGOUT]] command in direct mode.
The card code for ESC is multipunched 7-8-9.
A batch-input-file may contain any number of jobs and a job may use any number of batch-input-file / batch-output-file parts. Thus, the boundaries between jobs and batch-input-files are completely independent of each other.
