Explanation
：
This command is used to replace character n in current characters set to user-defined
character m. After using this command, the user-defined character m will be printed out
instead of character n in current characters set.
m1,m2……mk is user-defined character code.
n1,n2……nk is replaced character code in current character set.
Both the value of m and n should be 32~255. Subscript k should be 1~32. The largest
character number which can be replaced is 32. Character NUL is added at the end to mean
the command is over. Ref: ESC % and ESC : command.
Remark: No matter in Chinese mode or character mode, replacing character will be printed
when printing this character code.

This command is used to recover original character in character set. This character has been
replaced by user-defined character through command ESC % previously. However, the
used-defined character won’t be deleted from RAM and still can be used through ESC %
command.
The BASIC programs to observing the effect of ESC &, ESC % and ESC : commands are as
below:
10 LPRINT CHR$(27)
；
“W”
；
CHR$(8)
；
‘Enlarge 8times from Width and Height
