[Mecanim] How To Play Animation?

Hello Everyone i want to know how i can play Animation in Mecanim

At this moment i use this code

 using UnityEngine;
 using System.Collections;
 
 // Require these components when using this script
 [RequireComponent(typeof (Animator))]
 [RequireComponent(typeof (CapsuleCollider))]
 [RequireComponent(typeof (Rigidbody))]
 public class BotControlScript : MonoBehaviour
 {
     [System.NonSerialized]                    
     public float lookWeight;                    // the amount to transition when using head look
     
     public float animSpeed = 1.5f;                // a public setting for overall animator animation speed
     public float lookSmoother = 3f;                // a smoothing setting for camera motion
     public bool useCurves;                        // a setting for teaching purposes to show use of curves
 
     private Animator anim;                            // a reference to the animator on the character
     private AnimatorStateInfo currentBaseState;            // a reference to the current state of the animator, used for base layer
     private CapsuleCollider col;                    // a reference to the capsule collider of the character
     
 
     static int idleState = Animator.StringToHash("Base Layer.Idle");    
     static int locoState = Animator.StringToHash("Base Layer.Locomotion");            // these integers are references to our animator's states
 
     void Start ()
     {
         // initialising reference variables
         anim = GetComponent<Animator>();                      
         col = GetComponent<CapsuleCollider>();                
         if(anim.layerCount ==2)
             anim.SetLayerWeight(1, 1);
     }
     
     
     void FixedUpdate ()
     {
         float h = Input.GetAxis("Horizontal");                // setup h variable as our horizontal input axis
         float v = Input.GetAxis("Vertical");                // setup v variables as our vertical input axis
         anim.SetFloat("Speed", v);                            // set our animator's float parameter 'Speed' equal to the vertical input axis                
         anim.SetFloat("Direction", h);                         // set our animator's float parameter 'Direction' equal to the horizontal input axis        
         anim.speed = animSpeed;                                // set the speed of our animator to the public variable 'animSpeed'
         anim.SetLookAtWeight(lookWeight);                    // set the Look At Weight - amount to use look at IK vs using the head's animation
         currentBaseState = anim.GetCurrentAnimatorStateInfo(1);    // set our currentState variable to the current state of the Base Layer (0) of animation
 
 }
 }

i have Run Animation and Walk Animation and WalkBack how i can play These Animation? What is the Code To Play It
