Here there is 33 line. I need to make a fortran code which can
1. read the all data.
2. all the data situated between 1st column to 80 column. but it will be better if i can read till column 73(till alphabet P,S,D)
3. i have a code which can read and write only first column but i need to read all data.
_________________________________________________________________

program test
integer::i
character(15),allocatable,dimension(:):: line

!

!
OPEN( 1, FILE='text.igs')
OPEN( 2, FILE='l1.txt')

allocate( line(33))
do i=1,33
read(1,*)line(i)
write(2,*)line(i)
end do

end
_________________________________________________________
is it possible to get a solution in fortran??
Any body can help me please?

Is this homework for a course you are taking?

Thanks for your response SteamKing.
Ohh no. It is not a homework. i need to read the above described format file for my research. i think if i can read the file then i can write the above described file in my required way.

How much Fortran programming have you done?

 

[niloy112]

can do some numerical work but this kind of data processing it is problematic for me...:(

The best way to solve your input problem is to study Formatted input. Do you have a Fortran textbook available to study?
