most common insert/delete character operations affect only the
characters on the current line and shift characters off the end of the
line rigidly. Other terminals, such as the Concept 100 and the Perkin

Finally, you can specify <STRONG>dch1</STRONG> to delete a single character, <STRONG>dch</STRONG> with

A command to erase <EM>n</EM> characters (equivalent to outputting <EM>n</EM> blanks
without moving the cursor) can be given as <STRONG>ech</STRONG> with one parameter.
If there are commands to set and clear tab stops, they can be given as
