The code shown here is intended to be used on the Stanford {\sc SAIL} system,
and at other installations like CMU and ISI where essentially the same
extended character set is used. The fact that {\sc SAIL} has |'}'| in the
wrong place turns out to cause no difficulty in this case.

@<Set init...@>=
for i←1 to @'37 do xchr[i]←chr(i);
xchr[@'30]←chr(@'137);
xchr[@'32]←chr(@'33); {|not_equal| sign}
xchr[@'33]←chr(@'176);
