An oft-mentioned advantage of ALGOL over FORTRAN is the recursion capability of the former. FORTRAN adherents often belittle this advantage by claiming that all recursive relations can be reduced to recurrence or iterative relations, or that no recursive relations exist which are worth coding as recursive relations.
