Embedded format effectors
On ICL tapes, embedded format effectors (FEs) must appear and
begin within the first four bytes of the user portion of a record, and
comply with the restrictions previously stated under carriage control
conventions in order to be processed correctly. FEs that do not
comply with the restrictions do not cause any printer carriage control
action to occur, and normally print as a blank. A non-blank character
can be generated if the 'nn' portion of an embedded format is greater
than X‘80’.
Embedded format effectors, one or two bytes in length, are
composed of any combination of the following:
If X‘20nn’ causes the maximum line length to be exceeded, the line
is truncated to the maximum line length. Although format effectors
are processed from left to right, horizontal spacing FEs are
performed for the current line of data regardless of any vertical
spacing that follows. If a two-byte FE appears as the fourth byte of a
string of multiple FEs, it is processed normally.
