Subject: If Error Codes work by hand, but not with test script... (t16 failing)

If you replicate the test script's lines and the "printenv ?" produces the correct result and test 16 produces the wrong results make sure to look at note 4 in the spec. You might want to save errno before calling error exit. 1
