\section{Parameter table}
\label{PARAMETER_TABLE}

A parameter table is an ASCII formated file to convert code numbers to variable names.
Each variable has one line with its code number, name and a description
with optional units in a blank separated list.
It can only be used for GRIB, SERVICE, EXTRA and IEG formated files.
The {\CDO} option '-t $<$partab$>$' sets the default parameter table for all input files.
Use the operator 'setpartab' to set the parameter table for a specific file.
