Actually, I'm new in simulation project that I want to call another procedure from the following loop:

call.tcl

 source costtest1.tcl 
 for set x 5 $x <6 incr x 
 input_Protocol_pramerters 20 $x 2.0 $x 
 puts "Done"

The other procedure includes the following DSR protocol to generate the performance evaluation for simulation scenario:

costtest1.tcl

proc input_Protocol_pramerters No_node No_connaction Rate iter 
set cbr "cbr-"
set secn "scan-" 

append cbr $iter
append secn $iter
set DSR_fileTr "DSR"
append DSR_fileTr $iter ".tr"
set DSR_fileNam "DSR"
append DSR_fileNam $iter ".nam"
puts $iter
 #---- Generate Movement file ----
puts [eval exec "./setdest -v 1 -n $No_node -p 5 -M $No_connaction -t 100 -x 1000 -y 1000 >$secn"] 
 #---- Generate Movement file ----

puts [eval exec "ns cbrgen.tcl -type cbr -nn $No_node -seed 1.0 -mc $No_connaction -rate $Rate >$cbr"]
