```Pascal

function main (const p : int ; const s : int) : (list(operation) * unit) is

## Multiple entry points
|

|
|
|

|
|
Multiple entrypoints are currently not supported in Michelson, however with Ligo, you can work that around by using variants.

```Pascal

// variant defining pseudo multi-entrypoint actions

type action is
|
||
|
|
| Increment of int
|
||
|
|
| Decrement of int
|

|

function add (const a : int ; const b : int) : int is
|
||
|
|
block { skip } with a + b
|

|
|
|

function subtract (const a : int ; const b : int) : int is
|
||
|
|
block { skip } with a - b
|
||
|
|
|
||
|
|
// real entrypoint that re-routes the flow based on the action provided

function main (const p : action ; const s : int) : (list(operation) * int) is
|

block {skip} with ((nil : list(operation)),

case p of

| Increment n -> add(s, n)
|

| Decrement n -> subtract(s, n)
