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

platform::shell

platform::shell(n)					       Tcl Bundled Packages						platform::shell(n)

__________________________________________________________________________________________________________________________________________________

NAME

       platform::shell - System identification support code and utilities

SYNOPSIS

       package require platform::shell ?1.1.4?

       platform::shell::generic shell
       platform::shell::identify shell
       platform::shell::platform shell
_________________________________________________________________

DESCRIPTION

       The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.

       This  package  allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
       requirement is that the other shell (identified by its path), is actually executable on the current machine.

       While for most platform this means that the architecture of the interrogated shell is identical to the architecture of  the  running  shell
       this  is  not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
       32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.

       For applications like a code repository it is important to identify the architecture of the shell which will  actually  run  the  installed
       packages, versus the architecture of the shell running the repository software.

COMMANDS

       platform::shell::identify shell
	      This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::generic shell
	      This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::platform shell
	      This command returns the contents of tcl_platform(platform) for the specified Tcl shell.
