Hi

The doc for print\_term/2 says:

**operators** (+Boolean)  
This is the inverse of the [write\_term/3](https://www.swi-prolog.org/pldoc/man?predicate=write_term/3) option `ignore_ops`.

but the operators(false) behaves differently to write\_options([ignore\_ops(true)]):

```
?- print_term([div(1/3,7/6)],[operators(false)]).
[1/3 div (7/6)] <<< This seems wrong

?- print_term([div(1/3, 7/6)],[write_options([ignore_ops(true)])]).
[div(/(1,3),/(7,6))] <<< As expected

```

Thanks. The operators(Ops) and ignore\_ops(IgnOps) in write\_options must be consistent as print\_term/2 uses the first for the high level stuff and small terms are handled by the second. Implemented forced consistency, deprecated the operators(Ops) option and use the write\_options when given.
