C shell concatenate string doesn't work
I have the following code:

Code:
#!/bin/csh
clear
set cloud_file="/home/labs/koren/davidsr/general_scripts/MFP_10_PP_Parmas.txt" # to fill
set mie_tables_dir='/home/labs/koren/davidsr/SHDOM_MAIN/MIE_TABLES/non_polo_wave_0.7_water_50R_s0.5_e25_max_70.mie' # to fill
set prp_dir='${pp_dir}/pp_prp/'
set num_lwp=7 # to fill
set num_r=3 # to fill
#for each wavelength


foreach wav (0.7 1.61)
	echo "current wavelength is: $wav"
	set iter=1
	while ($iter <= $num_r)
		@ last_line=$iter * $num_lwp + $iter
		@ first_line=$last_line - $num_lwp
		@ second_line=$first_line + 1
		
		set R_eff=`awk "NR==$first_line {print}" $cloud_file`
		set LWP=`awk "NR==$second_line, NR==$last_line {print}" $cloud_file`
		@ iter++
		foreach r ($R_eff)
			set r=$r | tr "\n" " "
			set r=$r | tr "\r" " "
			echo "current radius is: $r"
			foreach lwp ($LWP)
				set lwp=$lwp | tr "\n" " "
				set lwp=$lwp | tr "\r" " "
				echo "current lwp is: $lwp"
                		# echo "${prp_name}"
                		# prp_name+="${prp_name}_Re_${r}"
                		# echo "${prp_name}"
                		# set prp_name3="${prp_name2}_wav_${wav}"
                		# echo "${prp_name3}"
				set prp_name="pp_LWP_${lwp}_Re_${r}_wav_${wav}.prp"
				echo "${prp_name}"
			end
		end
	end
end

which the cloud file looks like:
Code:
1.0
39.999
80.001
120.0
159.999
200.001
240.0
279.999
2.0
39.999
80.001
120.0
159.999
200.001
240.0
279.999

although it should print the prp_name as constructed above I get the following:
Code:
current radius is: 3.0
current lwp is: 39.999
_wav_1.61.prp
current lwp is: 80.001
_wav_1.61.prp
current lwp is: 120.0
_wav_1.61.prp
current lwp is: 159.999
_wav_1.61.prp9
current lwp is: 200.001
_wav_1.61.prp1
current lwp is: 240.0
_wav_1.61.prp
current lwp is: 279.999
_wav_1.61.prp9

I couldn't fix the issue, would appreciate some help

chsh

CHSH(1)                                                            User Commands                                                           CHSH(1)

NAME

       chsh - change login shell

SYNOPSIS

       chsh [options] [LOGIN]

DESCRIPTION

       The chsh command changes the user login shell. This determines the name of the user's initial login command. A normal user may only change
       the login shell for her own account; the superuser may change the login shell for any account.

OPTIONS

       The options which apply to the chsh command are:

       -h, --help
           Display help message and exit.

       -R, --root CHROOT_DIR
           Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR directory.

       -s, --shell SHELL
           The name of the user's new login shell. Setting this field to blank causes the system to select the default login shell.

       If the -s option is not selected, chsh operates in an interactive fashion, prompting the user with the current login shell. Enter the new
       value to change the shell, or leave the line blank to use the current one. The current shell is displayed between a pair of [ ] marks.

NOTE

       The only restriction placed on the login shell is that the command name must be listed in /etc/shells, unless the invoker is the superuser,
       and then any value may be added. An account with a restricted login shell may not change her login shell. For this reason, placing /bin/rsh
       in /etc/shells is discouraged since accidentally changing to a restricted shell would prevent the user from ever changing her login shell
       back to its original value.

FILES

       /etc/passwd
           User account information.

       /etc/shells
           List of valid login shells.

       /etc/login.defs
           Shadow password suite configuration.

SEE ALSO

       chfn(1), login.defs(5), passwd(5).
