ALTERNATE CHARACTER SETS
Appendix B
Your terminal can display symbols from three different character sets:
•
the Roman 8 set, consisting of Roman style letters
• the Math set, consisting of mathematical symbols
•
the Line-drawing set, consisting of various line segments
You may switch between these character sets on a character-by-character basis. For example,
you
may mix mathematical symbols within written text. You do this by defining different
portions of a line to contain symbols from the appropriate character sets. You may envision
each group of characters as a "field".
Selecting Alternate Sets
To use an alternate character set, you must first make the desired character set the active
character set. From the keyboard, you may select between the three character sets by using the
second level of the Video Enhancement function key labels. You access these keys by pressing:
... Ell
--
This keystroke sequence displays the following labels:

.. .. .. Ell

Pressing .. selects the Math set to be the active character set and simultaneously updates
the Al ternate Set field in the Terminal Configuration menu to "Math(A)". Pressing"
selects the Line-drawing set to be the active character set and simultaneously updates the
Alternate Set field in the Terminal Configuration menu to "Line(B)". Pressing ..
returns the terminal to the base character set, but leaves unchanged the setting of the
Al ternate Set field in the Terminal Configuration menu.
You may also select the various character sets programmatically. However, this is a two-step
process
as you first specify which character set is to be the alternate character set; then,
explicitly activate the alternate character set.
