Hi,
I have the followin input-file
------- ma2.input -----------------------------------
fallingPower : (INT,NNI) -> INT
fallingPower (p,0) == 1
fallingPower (p,n) == p*fallingPower(p-1,n-1)
test0 () ==
n : Matrix Integer
n := new(3,3,0)
for i in 1..3 repeat _
for j in 1..3 repeat _
n(i,j) := fallingPower(i+j,j)
n
test1 () ==
n : Matrix Integer
n := new(3,3,0)
for i in 1..3 repeat _
for j in 1..3 repeat _
n(i,j) := i+j
n
test2 () ==
n : Matrix Integer
n := new(3,3,0)
for i in 1..3 repeat _
for j in 1..3 repeat _
n(i,j) := fallingPower(i,j)
n
test2()
test1()
test0()

reading this in axiom gives the follwing error

Perhaps you should use "@" to indicate the required return type,
or "$" to specify which version of the function you need.
AXIOM will attempt to step through and interpret the code.

i can't see whats wrong with 'test0'.

ps: same result in fricas or open-axiom.
