Assumes directive cannot occur in the execution part of Fortran. See the following in Section 8.3.2 of OpenMP 5.2 standard. So it is not an executable directive.
```
The assumes directive may only appear in the specification part of a module or subprogram after any USE statement, any IMPORT statement, and any IMPLICIT statement.
```
