In case you don't know this, you can determine how many products are in the 
queue that match your request via this command:

    pqcat -f NMC2 -p 
"RUC2|prod/gfs.*[012]p[^2]|prod/rtma|ndfd|nccf/com/nam.*awip3d.*grib2" -o 99999 
>/dev/null

The redirection of standard output to "/dev/null" is *very* necessary if you 
value your terminal session. :-)

Steve Emmerson
