Hi,
one possibility is:

Inner[#1[#2] &, f, arg, List]

Rolf Mertig

===============================================
Dear MathGroup members,
I have a list of n unnamed functions

f = {expr1 &, expr2 &,... ,exprn &}
(each function has exactly one arguement.
and a list of n arguments.

arg = {arg1, arg2,... ,argn}

I simply want to apply each function expri &
to the respective argument argi in order 
to obtain the list of function values fi.
Is there no more elegant way than the following one?

Map[#[[1]][#[[2]]]&, Transpose[{f,arg}]

Thanks,
        Johannes
