If I declare the array function h1[k](x):=block(print(x)); and execute h1[1]([1,2]); it prints x, not [1,2] but the function returns [1,2]. Shouldnt it print [1,2], not x? I see this behavior in maxima 5.5, and Macsyma 2.4. Can anyone think of a work around for this or explain this behavior? Dan Stanger
