Turns out the method I originally suggested is unnecessarily cumbersome.
A more elegant method is described below.

Well, the limit is one: only one OMIT subcommand per COPY command.
That makes this procedure distinctly tedious, for 35 columns.
A more efficient method:
ADD c1-c35 c36
This puts the sum of c1-c35 in c36, but if any one (or more) of c1-c35
are missing, the result is missing: so c36 has '*' for every row where
there is a missing datum in some column(s). A reasonable next step is
to see how much data is left:
N c36
reports the number of non-missing values in c36. If that value is zero,
or some other very small number, you might want to re-think your
strategy before proceeding:
COPY c1-c35 c41-c75;
OMIT c36 '*'.
Columns c41-c75 now contain only rows of the original c1-c35 for which
all of the values are NON-missing.
