Escape-channel skip. This pair is an octal 77 followed by a 6-bit
binary 01xxxx (hexadecimal 3F followed by an 8-bit binary
0001xxxx). The escape-channel skip pair, when deleted from the
output print line, terminates the output print line and causes a skip to
channel operation after printing (where xxxx is the binary channel
number and 0 xxxx F). Characters following this pair, but preceding
the end of this logical record, are ignored. Input print lineOutput print

Escape-“other character”. This pair is an octal 77 followed by a 6-
bit 11xxxx (hexadecimal 3F followed by an 8-bit binary 0011xxxx),
where xxxx is not 1111. The pair is deleted from the output print line
and no other action occurs.
Data format with embedded control characters, normal edit mode (9 x 8 packed ASCII)
Embedded control characters appear within the print line image and
may appear singly or in pairs. These control characters must be
processed on a left-to-right scan basis.
Note: Hexadecimal character codes have the 9-bit octal character
packed into an 8-bit byte with the 9th (high order) bit dropped.
References to character codes refer to the character value prior to
translation to EBCDIC.
Single control characters
Ignore. The ignore character is an octal 177 (hexadecimal 7F). This
character is deleted from the print line when not preceded by escape-
escape paired control characters. That is, the print character
preceding the ignore character, and the print character following the
ignore character, are printed adjacent to each other.
