Tips
If you enter a CHANGES OFF command without a preceding
CHANGES ON command, TFORM issues an error message.
TFORM places change marks in the right margin, whether on a right-
hand page or a left-hand page. A change character appears one space
to the right of the right end of the line it marks (either the actual right
margin of the page or the adjusted right margin—changed by the
INDENT command, for example—whichever is farther to the right).
Indentation on the right side, print offset changes, or margin changes
can change the location of change marks.
You should have at least two character positions available to the right
of a line (either the effective right end of the line or the right margin of
the page, whichever is farther to the right) to allow TFORM to print the
change mark. If no space is available, TFORM issues an error message
and doesn’t print the character.
