[daip] TAFLG

[Joseph Lazio]

Hi,

I've set up TAFLG to remove all entries in a CC table having a flux
density less than some specified amount.  (The inputs are appended.)  

That's exactly what happens.  However, a listing of the table (PRTAB
example appended; PRTCC shows same thing) shows that the number of
rows in the table is unchanged.  (Yes, I've doublechecked BPRINT and
EPRINT; BPRINT=1, EPRINT=0, so I am seeing the entire table.)  In
further processing, other tasks (notably CALIB) apparently grabs the
number of rows from the table header, then collapses when it cannot
read that number of rows.

Is there a reason for not resetting the number of rows in the table?
