New Translator – Checking Token Codes

A minor coding issue was discovered in code that needs to check the code in a token.  This is more an issue with the new translator routines because they will be checking tokens that could be of any token type.  The old translator routines already knew the token type before checking the code.

Since it is desirable to make the code as easy to implement as possible, the Token class isCode() function was modified to make sure the token is the correct type before checking the code.  The correct type is any type that has a table entry.  If the calling code already knows the token is a type that has a valid code, then it can use the Token class code() access function and compare to the code directly.
