Can you guess?
When working for a company a large portion of whose business was with the US in the era of "self-documenting" code and with an 11 character variable name limit, we needed to name a flag to filter out the units which weren't selling in the US. The full name of the flag was:
commercial units nil in Greater US (i.e. incl Hawai and Alaska).
Can you guess what we set the variable name to?
