Host Mode Control Code Sequence Placement

A host mode control code change sequence conventionally follows a line terminator character and applies to the data occurring before the next line terminator character. The line terminator characters are line feed (LF), form feed (FF), vertical tab (VT), EVFU channels (10H to 1DH), and EVFU load codes (1EH and 1FH).

Valid Control Code Sequence

Valid Control Code sequences will be recognized anywhere in the data stream and interpreted as applying to the data occurring between the same two line terminators as the Control Code sequence.

The following examples are recognized as valid control code sequences. In each case, the data occurring between the line terminators will print in the mode specified by the control sequence.

(Line Terminator Previous Line) (Mode Change Control Code Sequence) (Data) (Line Terminator).

(Line Terminator Previous Line)(Data) (Mode Change Control Code Sequence)(Data) (Line Terminator).

(Line Terminator Previous Line)(Data) (Mode Change Control Code Sequence)(Line Terminator).

NOTE: The initial line terminator shown in the examples above is not a required part of any single programming line but would occur at the end of the preceding programming line. The only requirement for any single programming line is that the mode change Control Code sequence must occur before the line terminator for that line.

If more than one one valid mode change control code sequence occurs between two line terminators, the last one will take precedence.
