;Task
▲An extended Straddling Checkerboard, is like the regular [[Straddling checkerboard]], but allows word dictionaries and arbitrary functional codes like (FIGURE, where you can specify a number literally).
Implement encoding and decoding of a message using the extended straddling checkerboard, CT-37w, described in the reference below.
You may switch the codes for F/L (99) and SUPP (98) to help differentiate the code for '9' from that of '999'. So we would then have F/L (98) and SUPP (99).

There is no need to create a word dictionary for CODE (6). It suffices to just include CODE followed by some 3 digit number in the message to be encoded.
Test your solution by encoding and decoding the message:
'Admin ACK your MSG. CODE291 SEND further 2000 SUPP to HQ by 1 March'
