The printer control options CTLASA and CTL360 apply only to OUTPUT files associated with consecutive data sets. They specify that the first character of a record is to be interpreted as a control character.
>>-+-CTLASA-+-------------------------------------------------->< '-CTL360-'
The CTLASA option specifies American National Standard Vertical Carriage Positioning Characters or American National Standard Pocket Select Characters (Level 1). The CTL360 option specifies IBM machine-code control characters.
The American National Standard control characters, listed in Figure 30, cause the specified action to occur before the associated record is printed or punched.
The machine code control characters differ according to the type of device. The IBM machine code control characters for printers are listed in Table 17.
