If a variable can take n values should we check for the validity of the values or assume that if all the n-i checks fail it would be the nth value.

For example if we have a variable that stores gender as M or F

If gender = "M"

do male_processing

else

do female_processing

endif

If gender = "M"

do male_processing

else

if gender = "F"

do female_processing

else

print "Something has gone wrong Gender has a value " Gender

endif

endif
