093. Fortran 2008 introduced IMPURE ELEMENTAL procedures

topic: Procedures

Note

This tip is a draft1.

Fortran 2008 allows procedures to be labeled IMPURE ELEMENTAL. Such procedures can do external I/O and have a STOP or ERROR STOP statement. They can simulate a loop over a collection. The plain ELEMENTAL designation means the same as PURE ELEMENTAL.
