# ;, :, _stmtseq

Statement sequences

### Use only in the MuPAD Notebook Interface.

This functionality does not run in MATLAB.

## Syntax

````object1; object2; ...`
`object1: object2: ...`
_stmtseq(`object1, object2, …`)
```

## Description

The function call `_stmtseq (object1, object2, ...)` is equivalent to the statement sequence `(object1; object2; ...)`.

The function call `_stmtseq (object1, object2, ...)` evaluates the statements `(object1; object2; ...)` from left to right.

`_stmtseq ()` returns the void object of type `DOM_NULL`.

## Examples

### Example 1

Usually, statements are entered imperatively:

`x := 2; x := x^2 + 17; sin(x + 1)`

This sequence of statements is turned into a single command (a "statement sequence") by enclosing it in brackets. Now, only the result of the "statement sequence" is printed. It is the result of the last statement inside the sequence:

`(x := 2; x := x^2 + 17; sin(x + 1))`

Alternatively, the statement sequence can be entered via `_stmtseq`. For syntactical reasons, the assignments have to be enclosed in brackets when using them as arguments for `_stmtseq`. Only the return value of the statement sequence (the return value of the last statement) is printed:

`_stmtseq((x := 2), (x := x^2 + 17), sin(x + 1))`

Statement sequences can be iterated:

`x := 1: (x := x + 1; x := x^2; print(i, x)) \$ i = 1..4`

`delete x:`

## Parameters

 ```object1, object2, …``` Arbitrary MuPAD® objects and statements

## Return Values

Return value of the last statement in the sequence.
