This feature is now standardized with keywords IOMSG=3D for I/O routines, keyword ERRMSG=3D for memory and image control routines and the optional argument CMDMSG is defined in EXECUTE_COMMAND_LINE subroutine. I encounter these days some difficulties with the subroutine GET_ENVIRONMENT_VARIABLE and discovered that this subroutine doesn=92t implement any means to retrieve =93error message=94 from the host processor although the optional argument STATUS is defined. So, I put to WG5 the following requirement written by analogy with EXECUTE_COMMAND_LINE subroutine : Note that you may receive this mail twice due to a change in my mail address ; sorry for that !! =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Add the optional argument CMDMSG in subroutines GET_COMMAND , GET_COMMAND_ARGUMENT and GET_ENVIRONMENT_VARIABLE with this edit : CMDMSG (optional) shall be a default character scalar. It is an INTENT (INOUT) argument. If an error condition occurs, it is assigned a processor-dependent explanatory message. Otherwise, it is unchanged.=20 =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Dr. Bernard PICHON (from France)=20 CNRS =96 Observatoire de la C=F4te d=92Azur (OCA)
