Set or get Flags to reduce or extend the output level
of print_order.

a := OrderPrintFlags();</pre>

<h3>
Description:
</h3>
OrderPrint can be used to set or get Flags, which are saved
in a record. The record entrys can be the following
\begin{tabular}{l|c|l}
name & type & description
disc & int & information about discriminant
reg & int & information about regulator
fac_disc & int & information about factorizing
unit & int & information about units
index & int & information about index

class_group& bool & information about class group
class & bool & information about class number
trafo & bool & information about transform. Matrix
trafo_inv & bool & information about inverse Trafomatrix
trafo_den & bool & information about Matrix denominator
galois & bool & information about galois groups
sign & bool & information about sign
autom & bool & information about automorphisms
\end{tabular}

where
number = -1: maximal output
number = 0: no output
number = \langle any number rangle: prints if length of output
string is less or equal then
num-
\hspace*{3.92cm} ber, otherwise prints "Known"
and
bool = true: prints if known
bool = false: prints nothing

To get the settings call OrderPrintFlags();

Example:
</h3>
Set output level of unit and signature to 0 (prints nothing) even
if unit or signature are known.
