Bug ID: 96583 Summary: F2018 changes to get_environment_variable Product: gcc Version: 11.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: markeggleston at gcc dot gnu.org Blocks: 85836 Target Milestone: --- Fortran 2003 and Fortran 2008: Arguments LENGTH and STATUS shall be default integer scalars. Fortran 2018: Arguments LENGTH and STATUS shall be a scalars of type integer with a decimal exponent range of at least four. New argument: ERRMSG (optional) shall be a default character scalar. It is an INTENT (INOUT) argument. It is assigned a processor-dependent explanatory message if the optional argument STATUS is, or would be if present, assigned a positive value. Otherwise, it is unchanged. Not currently supported by gfortran 11. --- For -std=f2003 and -std=f2008 LENGTH and STATUS arguments should be rejected if they are not default integer scalars, gfortran 11 produces "type mismatch in argument" error messages. For -std=f2018 and -std=gnu LENGTH and STATUS arguments should only be rejected if the is integer(1).
