The TRANSLATE function returns unchanged in the output string all
characters from the source string that have no corresponding character in
the key string.
The TRANSLATE function deletes from the output string all source
characters that appear in the key string, but for which there is no
corresponding character in the replacement string. For example:
\TRANSLATE("James","am","on")
returns the string “Jones” .
You can use metacharacters (such as \> or \#) except the comment
metacharacter (\!) in either the key string or the replacement string.
TFORM treats them as single characters. Remember that if you want to use
a character that is the same as the trigger character, you must double it to
make TFORM treat it as a text character. (S)
