# PetscObjectSetTabLevel

Sets the number of tabs that ASCII output for that object use

### Synopsis

    #include "petscsys.h"
    PetscErrorCode  PetscObjectSetTabLevel(PetscObject obj,PetscInt tab)

Not Collective

### Input Parameters

| obj | - any PETSc object, for example a Vec, Mat or KSP. Thus must be cast with a (PetscObject), for example, PetscObjectGetComm((PetscObject)mat,&comm);
| tab | - the number of tabs

Notes: this is used to manage the output from options that are imbedded in other objects. For example the KSP object inside a SNES object. By indenting each lower level further the heirarchy of objects is very clear.
