balance := 1000 %assigning variable a value
font1 := Font.New ("Lucida Console:32:Bold")
font2 := Font.New ("Lucida Console:14")



procedure Deposit %start of procedure
    var deposit : real %declaring all variables
    put "DEPOSITS" %Title of the procedure
    put ""
    put ""
    put "Enter amount of deposit: " .. %Asking for user input
    get deposit %user input
    balance := balance + deposit %adding deposit to the balance
    put "Current balance: $", balance %outputing the new balance
end Deposit %end of procedure



procedure Withdrawal %start of the procedure
    var withdrawal : real %decalre all variables
    put "WITHDRAWALS" %tile fo the procedure
    put ""
    put ""
    put "Enter amount of withdrawal: " .. %asking for user input
    get withdrawal %user input
    if withdrawal <= balance then
        %start of the outer if statement-only condition
        if withdrawal rem 10 = 0 then
            %start of the innter if statement-first condition
            balance := balance - withdrawal
                %takes amount of money out of the withdrawal
        else %for the error message
            put "Invaild amount(most be a multiple of 10)"
        end if
    else %if the balance is less than withdrawal
        put "Insufficient Funds"
    end if %end of the if statements
    put "Current balance: $", balance : 0 : 2
        %displays balance after withdrawal
end Withdrawal %end of procedure

ye, i wouldn't use procedures, it'll help if u use case statements, with a menu before it and a loop around everything so that you can actually exit.

Also, put the loop above the variable in the main program.

I made a mistake and submitted the same message twice. what I really mean to say is after this one.

A delay and a cls at the end of the loop woudn't hurt either. After that you should be fine.
