Our version of awk does not allow one to use a field specified
by a numerical expression as the left hand side of an expression.

The file below will pass the standard input through unmodified,
although it is designed to replace the last field in each record
with "LAST FIELD".  Is this a bug or a feature?
 -----------------------
 { $NF = "LAST FIELD"
 print}

Must be a bug; it works here (SVR2 + bug fixes).
Make sure the shell does not mess with the special characters
(enclose the whole expression in 'quotes').

This works fine for me,  so you must have a bug in your release.
