$6.(30$ Points$)$ Write a Marie SUBROUTINE named $$Check$$ that will get a decimal value from the Accumulator and validate that the value is not negative and not greater than $1000.$ If the value is valid, return the value in a variable named $$Result$.$ If the value is not valid, return $0$ in the $$Result$$ variable. Return to the location immediately after the $$Call Check$$ instruction that called the Subroutine. You can define any variables needed. $($Like Result and X$1000.)$
