I want to access a certain range of the data, e.g. print $3 when the following conditions are met:
PHI 50 to 100 and PSI -70 to -90

which would give the following data:

Try:
Code:
awk '$1>=50&&$1<=100&&$2>=-90&&$2<=-70' file

Ok, thanks, now my output data is of the form:

Code:
4.61531
4.59969
4.45344
4.245
4.24344
4.0775
3.90438
3.86375
3.84125
3.76875
3.63406
3.39844
3.73563
3.65938
3.60906
3.31
3.73688
3.61813
3.45938
....etc...

and I have called the two data files I have c7eq.dat (dimension 25:1) and c7ax.dat (dimension 41:1)



In my Fortran program I wish to process this data:

Code:
Program average_2
      implicit none
      double precision, dimension (25:1) :: H
      double precision, dimension (41:1) :: G

      open (unit=2, file="c7eq.dat", form="unformatted")
      read (2) G
      open (unit=3, file="c7ax.dat", form="unformatted")
      read (3) H

However I get the error:
forrtl: severe (24): end-of-file during read, unit 2, file /home/guest/c7eq.dat

Anyone can help me here?
