All,

   I got the solution from another source. The
script below can be replaced with a single
command:

echo $line | awk '{for (i=1; i<NF; i+=7) print $i,$(i+2),$(i+5)}'

Thanks,

All,

   I am trying to variablize the print portion
of the awk command. The reason for this is
processing a variable length string. The
string will be 7 fields long, and I need fields
1, 3, and 6 respectively. The set would be as
follows:

1 3 6
8 10 13
15 17 20
...

NNET is the number of sets of 7 in the string

#############################################
      i=1
      FACTOR=0
      while [ "$NNET" -ge "$i" ]
         do
         let k=1+$FACTOR
         let l=3+$FACTOR
         let m=6+$FACTOR
         echo $line | awk {'print $$k,$$l,$$m'}
         let FACTOR=$i*7
         let i=$i+1
      done
#############################################

Thanks,

John T. Mills
