Functions in a switch statement

Is there a way to put functions into a switch statement? i would like to use a switch statement for the lift i have as an example here, but im at a loss right now. i guess i mainly need to know how to set up a variable for this.

Here is what i have so far

#pragma config(Motor, port1, Lift1, tmotorVex393_HBridge, openLoop)
#pragma config(Motor, port2, Lift2, tmotorVex393_MC29, openLoop)
#pragma config(Motor, port3, Lift3, tmotorVex393_MC29, openLoop)
#pragma config(Motor, port4, Lift4, tmotorVex393_MC29, openLoop)
//!!Code automatically generated by ‘ROBOTC’ configuration wizard !!//

void LiftPower(int power){
motor(Lift1) = power;
motor(Lift2) = power;
motor(Lift3) = power;
motor(Lift4) = power;
}

task main()
{

	switch(){		
		case 1:
			LiftPower(127);
		break;
		
		case 2:
			LiftPower(-127);
		break;
		
		default:
			LiftPower(0);
		break;
	
}

}

Yes you can call functions from within a switch statement.

The switch statement needs a variable to decide which branch it takes. You should place the whole thing in a while loop if this is part of some driver control code.

#pragma config(Motor, port1, Lift1, tmotorVex393_HBridge, openLoop)
#pragma config(Motor, port2, Lift2, tmotorVex393_MC29, openLoop)
#pragma config(Motor, port3, Lift3, tmotorVex393_MC29, openLoop)
#pragma config(Motor, port4, Lift4, tmotorVex393_MC29, openLoop)
//*!!Code automatically generated by 'ROBOTC' configuration wizard !!*//

void LiftPower(int power){
  motor(Lift1) = power;
  motor(Lift2) = power;
  motor(Lift3) = power;
  motor(Lift4) = power;
}

task main()
{
  int action = 0;
  
  // put everything in a while loop
  while(1) {
      // now set action in some way, we could use a button
      // this will just change it betweeen 0 and 1
      // you can figure out what other values it could have
      action = vexRT Btn6U ];
      
      switch( action ){
      case 1:
        LiftPower(127);
        break;
    
      case 2:
        LiftPower(-127);
        break;
    
      default:
        LiftPower(0);
        break;
      }
      
    wait1Msec(10);  
  }
}
