Assuming the + sign means concatenate (as it does for Python lists) rather than add (as it does for Numeric or Numarray arrays), it would be ([3,1,4,1,5,9] indexbase 0) since 0 would still be the default indexbase. If the user wanted a 1-based list as a result, he would use an expression such as (([3, 1, 4] indexbase 0) + ([1, 5, 9] indexbase 4) indexbase 1) If + means add, the result would be ([4,6,13] indexbase 0) . Adding arrays makes sense if they have the same number of elements -- they do not need to have the same indices. I rarely see problems caused by flexible lower array bounds mentioned in comp.lang.fortran . -- http://mail.python.org/mailman/listinfo/python-list
