Ted Clarke is undertaking the enhancement of the WordsWorth Compendium's words and phrases to portray them in a number of forms, such as:

1.  normal words

2.  word with letters in reverse order 

3.  alphwords 

4.  isomorphic codings 

5.  gematric codings 

For example:

BEERBIBBER  REBBIBREEB  BBBBEEEIRR  1223141123  68

The third and fourth forms clearly show that beerbibber is also a Pascal word.
