When building a script, says semicolon is missing.

I wrote this script:

var moveSpeed - 1.0; var turnSpeed - 1.0;

function Update() { /
if(Input.GetButtonDown("Jump")) { transform.position.z += 1.0; } /

 if(Input.GetButton("W"))
 {
     transform.position += transform.foward * moveSpeed * Time.deltaTime;
 }
 if(Input.GetButton("S"))
 {
     transform.position += -transform.foward * moveSpeed * Time.deltaTime;
 }
 if(Input.GetButton("A"))
 {    
     transform.eulerAngles.y += -turnSpeed * Time.deltaTime;
 }
 if(Input.GetButton("D"))
 {
     transform.eulerAngles.y += turnSpeed * Time.deltaTime;
 }

}

And when I try to build it, it gives me errors for the top two lines saying that I'm missing semicolons. What do I do?
