# DMSetOutputSequenceNumber
Set the sequence number/value for output 
## Synopsis
```
#include "petscdm.h"          
#include "petscdmlabel.h"     
#include "petscds.h"     
PetscErrorCode DMSetOutputSequenceNumber(DM dm, PetscInt num, PetscReal val)
```

## Input Parameters

- ***dm -*** The original `DM`
- ***num -*** The output sequence number
- ***val -*** The output sequence value





## Note
This is intended for output that should appear in sequence, for instance
a set of timesteps in an `PETSCVIEWERHDF5` file, or a set of realizations of a stochastic system.
