This example creates the
inverse of the translation table that was created
in Editing by Using a Quoted Character for Starting Position.
The new translation table that is created in this example is the operating
environment-to-device translation for use in data communications.

The INVERSE statement lists in the SAS log all of the multiple translations
that it encounters as it inverts the translation table. In
Editing by Using a Quoted Character for Starting Position, all the
lowercase letters were converted to uppercase in the translation table UPPER,
which means that there are two sets of uppercase letters in UPPER. When INVERSE
cannot make a translation, PROC TRANTAB fills the value with 00. Note that
the inverse of the translation table UPPER has numerous 00 values.
