Functions doesn't work - NodeJs -

I have an issue , my functions don't work , I don't know why ?

my code is an interpreter with Nodejs to control a ROBOT to move forward , backward & jump .

This is my code :

/*jshint node: true */
"use strict"; 

var fs = require('fs'); 
var filename = "./robot.txt"; 
var command =  null ; 
var x= 0 , y = 0 , r = 90 , j = 0  , n= 0  , le= 0 , ri= 0 , rep = 0 ,  end = 0, lr= 0 , f = 0 , i= 0 , okC = 0 , b = 0 , t= 0 ; 

try{
        command = fs.readFileSync(filename).toString().split('\r\n'); 
}
catch(e){
        console.error("I can't read from the file " +e); 
}

var line = []; 

robotInterpreter(command); 
console.log('OK' , ' ' + x + ',' + y + ',' + r); 
function robotInterpreter (value){
        for (var i in value) {
                var okC =0 ; 
                var a = value[i].trim(); 

                line.push(a.split(' ')); 
                for(var j in line){
                        if(okC === 0)
                                verificationOfCommand(line[i][j]);
                }

                if (okC === 1){
                        if (rep === 0){
                                  var c  =  a.substring(n).trim().split(',');
                                if(f === 1) verificationOfF(c) ;
                                if(b === 1) VerificationOfB(c) ;

                        }

        while(k >= 360){
                k = k - 360 ; 
        }
        if (r - k < 0 )
                r = 360 - (k-r); 
        else 
                r = r - k ; 
        if (r === 360)
                r = 0 ; 
}

function jump(var1, var2){
        x = parseInt(var1); 
        y = parseInt(var2); 
        j = 0;
}

The robot.txt contains :

# Move
FORWARD 200
COMMAND_WITH_ERROR 
BACKWARD 10

and it should print :

OK 200, 0, 90
ERROR LINE 2: Unknown command COMMAND_WITH_ERROR
OK 190, 0, 90

but my program prints only : x= 0 , y = 0 , r = 90

Anything wrong ?

PS : I used jshint and i got this error :

intersting.js: line 39, col 33, 'c' used out of scope.
