Thanks very much for the prompt response, works a treat. I need the latter but it's an initialisation thing so efficiency is not an issue.

If for example
M = lists,
F = seq,
you can write
apply(M, F, [1, 5])
The latter is quite expensive and should only be used when the number
of arguments isn't known at compile time.
