The command that uses IN, OUT, and INOUT parameters is a Stored Procedure in SQL (Structured Query Language).

Here's a step-by-step explanation:

1. IN parameter: This is the default type of parameter in a stored procedure. It allows the caller to pass a value into the procedure. The procedure cannot change the value of the parameter.

2. OUT parameter: This type of parameter allows the stored procedure to pass a value back to the caller. The caller must provide a variable to hold the value, and the procedure can then change the value of this variable.

3. INOUT parameter: This is a combination of IN and OUT parameters. It allows the caller to pass a value into the procedure, and also allows the procedure to pass a value back out to the caller.

Here's an example of a stored procedure using IN, OUT, and INOUT parameters:

```sql
CREATE PROCEDURE calculate(IN val1 INT, IN val2 INT, OUT sum INT, INOUT avg DECIMAL(5,2))
BEGIN
SET sum = val1 + val2;
SET avg = (val1 + val2) / 2;
END;
```

In this example, `val1` and `val2` are IN parameters, `sum` is an OUT parameter, and `avg` is an INOUT parameter.
