Fortran Condition handling semantics

Fortran language syntax provides limited error handling through the ERR and IOSTAT specifiers that can be coded on Fortran I/O statements, and the STAT specifier that can be coded on Fortran ALLOCATE and DEALLOCATE statements. When ERR, IOSTAT, or STAT are present on a statement, and an error is detected, Fortran semantics take precedence over Language Environment condition handling and control returns immediately to the Fortran program.

Language Environment does not support the use of the Fortran global error option table or extended error handling services.
