## Function Syntax

* `gmLanSetPID(gmLanMessage msg, long v);`
* `gmLanSetSourceId(gmLanMessage msg, long v);`
* `gmLanSetPrio(gmLanMessage msg, long v);`
* `gmLanGetPID(gmLanMessage msg);`
* `gmLanGetSourceId(gmLanMessage msg);`
* `gmLanGetPrio(gmLanMessage msg);`

## Description

* `gmLanSetPID` sets the parameter ID of the message.
* `gmLanSetSourceId` sets the source address of the message.
* `gmLanSetPrio` sets the priority of the message.
* `gmLanGetPID` gets the parameter ID of the message.
* `gmLanGetSourceId` gets the source address of the message.
* `gmLanGetPrio` gets the priority of the message.

## Parameters

* **msg**: Message
* **v**: Parameter ID, source address or priority

## Return Values

* `gmLanSetPID`, `gmLanSetSourceId`, `gmLanSetPrio`: —
* `gmLanGetPID`, `gmLanGetSourceId`, `gmLanGetPrio`: Parameter ID, source address or priority

## Example

A GMLAN message is modified and sent with **output(msg)**.\
The parameter ID is set with selector **gm\_pid**.

```plaintext theme={null}
gmLanMessage * msg1 ={SA =0x44, PRIO=  0x7,  gm_pid=0x11};
gmLanSetSourceId(msg1,0x55);
gmLanSetPID(msg1,0x11);
gmLanSetPrio(msg1,0x5);

output(msg1);

write("pid: 0x%x, source: 0x%x, prio:  x%x",gmLanGetPID(msg1),gmLanGetSourceId(msg1),gmLanGetPrio(msg1));
```

Priority and source address are copied from **Battery\_Voltage** message to the new message **msg**:

```plaintext theme={null}
on gmlanmessage  Battery_Voltage
{
  gmlanmessage Battery_Voltage msg;
  msg = this;  // SA and PRIO are not copied
  gmLanSetSourceId(msg, gmLanGetSourceId(this));
  // Copy  source address from Battery_Voltage to msg
  gmLanSetPrio(msg,  gmLanGetPrio(this));
  // Copy priority from Battery_Voltage to msg
  ...
}
```
