Fortran Fortran on ubuntu using f95 code help

[bkent9]

I have the following code with error- I want this general flow. Errors I get are missing ')' at the do while line,
syntax error on the line started with ****(not part of program added after fact)
and expecting END Program statement at line end do

counter=1
user_reaction =3
do while (counter .le. 3 .and. user_reaction .ne. 1 .and. user_reaction .ne. 2)

counter= counter+1
print *, "What reaction would like to look at:"
print *, "1)GP to EP"
print *, "2)GP to Klo"
if (counter.eq. 3) then
**** print *, "Please type a '1' for reaction GP to EP" &
"and '2' for the reaction GP to Klo"
end if
read *, user_reaction
end do
if (user_reaction .ne. 1 .and. user_reaction .ne. 2)
print *, "Failed to get a valid result. Program terminates in error."
STOP
end if

still seeing an error. something else must be off. here is the whole (non commented out) program. I am compiling using the command f95 -o extract extract_file.f

program extract_file

C this program is designed to obtain data from the two files for my two reactions

C user input variables
integer user_reaction
double precision user_energy, user_binWidth
integer counter

c values obtained from data files are stored in these variables
integer num_data_at_mmtm
integer r
real momentum_val
integer gpep, gpklo, SGTi, DSGi
real min_energy(2)
character headerline*50, obs*3 !there is a headerline that I don't want
! obs=observable for given data

C file names and creation
character directory*24
character*9 subdirectory(2)
character*10 filename(2)
directory = '/home/usersname/Desktop/' !usersname entered later on--> temp line
subdirectory(1) = 'GP to EP'
subdirectory(2) = 'GP to KLo'
filename(1) = 'gpep072211'
filename(2) = 'gpkl060311'
c open (unit=gpep,file=filename(1),blank='null')
c open (unit=gpklo,file=filename(2),blank='null')
c open (unit=SGTi,file=gpep_SGT,status='new')
c open (unit=DSGi,file=gpep_DSG,status='new')

C this section pertains to user selected reaction type to analyze
counter=1
user_reaction =3
do while ((counter .le. 3) .and. (user_reaction .ne. 1) .and. &
(user_reaction .ne. 2))

counter = counter + 1
print *, "What reaction would like to look at:"
print *, "1)GP to EP"
print *, "2)GP to Klo"
if (counter.eq. 3) then
print *, "Please type a 1 for reaction GP to EP", &
"and 2 for the reaction GP to Klo"
end if
read *, user_reaction
end do
if ((user_reaction .ne. 1) .and. (user_reaction .ne. 2)) then
print *, "Failed to get a valid result. Program terminates in error."
STOP
end if
stop
return
end program extract_file

Try gfortran. Also, why you get the missing ) error is because fortran code can only be 71 or 81 (I can't remember) column spaces long. You need to do a continuation.

Works perfectly OK (compiles without any errors) in gfortran on Ubuntu 12.04.
