What is CF-lang

CF-lang is a General Infantry's programming language, Let's kill all the enemy!

Examples

HelloWorld:

DEFENSE POSITION!   /* Main begin */
   FIRE!            /* nop */
   REPORTING IN "Hello World"!  /* print "Hello World */
   FIRE IN THE HOLE!  /* exit */
MISSION SUCCESS!    /* Main end */

endless loop:

DEFENSE POSITION!           /* Main begin */
   FIRE!                    /* nop */
   I AM IN POSITION A : 1!  /* A = 1 */
   FOLLOW ME!               /* end assign */
   REPORTING IN A!          /* print A */
   KEEP YOUR FIRE <A>!      /* while A */
       REPORTING IN "Go-to-hell!"!     /* print "Go-to-hell" */
   HOLD YOUR FIRE!          /* end while */
   FIRE IN THE HOLE!        /* exit */
MISSION SUCCESS!            /* Main end */

FizzBuzz:

DEFENSE POSITION!        /* Main begin */
    FIRE!                /* nop */
    I AM IN POSITION A : 0!   /* A = 0 */
    FOLLOW ME!           /* end assign */
    KEEP YOUR FIRE <A <= 100>!   /* while A <= 100 */
        WAIT FOR MY GO <A % 3 == 0>!    /* if A % 3 == 0 */
            REPORTING IN "Fizz"!        /* print "Fizz" */
        GO!GO!GO!                       /* end if */
        WAIT FOR MY GO <A % 5 == 0>!    /* if A % 5 == 0 */
            REPORTING IN "Buzz"!        /* print "Buzz" */
        GO!GO!GO!                       /* end if */
        MOVE ON A!         /* A -= 1 */
    HOLD YOUR FIRE!        /* end while */
    FIRE IN THE HOLE!      /* exit */
MISSION SUCCESS!         /* Main end */
