In the OP's example the values were Y/N, so a direct conversion to *ON/*OFF
seems justified. Agree if other values exist that do not collapse into a
binary condition.

Our ERP system stores Y/N flags in the database. The assumption it makes is
a value is true only if the condition is Y. An N or blank results in false.
Again, agree it depends on the defined values and assumptions an application
makes.

Need to be very careful here. myFlag may have additional values not
represented. For example, if the field is initialized to spaces (as
defaulted or otherwise), it does not equal "Y" and does not equal "N". A
later test of "myFlag = 'Y'" won't have the expected result if not
initialized. So we would first need to ensure that it's already being
initialized within the program, or that we completely understand the
ramifications of our change. Come to think of it we need to be sure of the
initialization in any case.
