Dear Newsgroup,

I'm in trouble with a recursive function. the functios looks similar to 
test[a_, b_] := test[a - 1, b]*b. A is the index b should just be an 
argument of test.
for any calculation i need to tell mathematica the first value of the 
function, e.g. test[0, 5]=5. The problem is the following: the first 
object is independent of b. does anyone know a way to tell mathematica 
the following thing:

  test[0,b]=5 => test[0]=5 regardless to b.

Thanks for your help.

Frank
