! Program to test arrays
! The program outputs a series of numbers.
! Two digit numbers beginning with 0, 1, 2 or 3 is a normal.
! Three digit numbers starting with 4 indicate an error.
! Using 1D arrays isn't a sufficient test, the first dimension is often
! handled specially.
! Fixed size parameter
