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

SONIC(1)						      General Commands Manual							  SONIC(1)

NAME

       sonic - Speech speed manipulator

SYNOPSIS

       sonic [OPTION]... inFile outFile

DESCRIPTION

       Sonic  is  used	to make wav files of speech faster or slower.  The primary advance in sonic is the ability to speed speech up by much more
       than 2X, with minimal distortion.  However, sonic can be used for both speeding up and slowing down speech files.  Additionally, sonic  can
       change the pitch and volume.

OPTIONS

       -c     Modify  pitch by emulating vocal chords vibrating faster or slower.  This causes more distortion than the default pitch scaling, but
	      sounds more like the same person trying to talk higher or lower.	The default pitch changes makes the voice sound like a	larger	or
	      smaller person, but introduces little distortion.

       -p pitch
	      Set pitch scaling factor.  1.3 means 30%% higher.

       -q     Disable  all  speed-up  heuristics, possibly improving the quality slightly.  This is mainly used for debugging the speed-up heuris-
	      tics.

       -r rate
	      Adjust the speed of playback.  This sales both the pitch and speed equally.

       -s speed
	      Set speed up factor.  1.0 means no change, 2.0 means 2X faster.

       -v scaleFactor
	      Scale volume by scaleFactor.  1.5 increases by 50%.  Clips if the maximum range is exceeded.

EXAMPLES

       sonic -s 3.2 book.wav book_fast.wav

       The above command would increase the speed of an audio book called book.wav by a factor of 3.2, and write the result in book_fast.wav.

       sonic -s 0.5 -v 1.5 spanish.wav spanish_slow.wav

       This would slow down the file spanish.wav by a factor of 2, make the volume 50% louder, and write the result to spanish_slow.wav.

       sonic -p 2.0 low.wav high.wav

       This would make a low voice sound very high pitched.
