(j3.2006) Fortran 2008 "ALL STOP" and exit status code

[Tobias Burnus]

Hello,

 From the Fortran 2008 draft standard:

"Execution of a STOP statement initiates normal termination of 
execution. Execution of an ALL STOP statement initiates error 
termination of execution."

NOTE 8.28: "If the stop-code is of type character or does not appear, or 
if an END PROGRAM statement
is executed, it is recommended that the value zero be supplied as the 
process exit status, if the
processor supports that concept."

As "ALL STOP" initializes an "error termination" should one not then 
recommend to return a non-zero status for stop codes of the type character?


Additionally, it is not fully clear to me whether STOP and ALL STOP stop 
a single image or all images. "When an image is terminated by a STOP or 
ALL STOP statement" implies that it only stops a single image; however, 
"ALL STOP" implies by its name that all images are stopped.
