Corrigenda: “Two FORTRAN Packages for Assessing Initial Value Methods”

There are typographical errors in the two formulas at the bottom of page 269. The test functions fi and f4 should end with +(1-xJ2, +(1-xpy (the minus signs should be pluses). Reference [ll] at the bottom of page 25 should be [lo]. On line 5 of page 254, replace " step 4.5 " by " step 5 " (there is no step 4.5 in the algorithm).
