Introduction This paper is a fresh request for two of the interpretations requested in 19-181. 19-240 and 19-241 explain why the editor did not accept them. Here, we make a fresh request to address the same problem. It is self-contained and does not require the reader to consult 19-181, 19-240, or 19-241. 2. Questions 11.6.9 FORM TEAM statement, paragraph 2 says "Successful execution of a FORM TEAM statement creates a new team for each unique team-number value specified by the active images of the current team." Successful execution precludes the case where the team contains failed images, see 11.6.11, so why does the adjective "active" appear here? 11.6.9 FORM TEAM statement, paragraph 6 says "If execution of a FORM TEAM statement assigns the value STAT_FAILED_IMAGE to the stat-variable, the effect is the same as for the successful execution of FORM TEAM except for the value assigned to stat-variable." How can this be correct in the presence of failed images? Is the intention that the effect is the same as if the team had consisted just of the active images? Do any of the new teams contain failed images? 3. Suggested response The text in 11.6.8 was originally written when we regarded the execution of a FORM TEAM statement in a team including failed images as successful as long as no other errors occurred. Paragraph 2 is about successful execution but actually describes both situations. It would be much clearer to do this rather than have paragragh 6 describe execution with failed images by referring back to paragraph 2. In particular, it makes it clear that in the STAT_FAILED_IMAGE case the new team does not include the images that were detected as failed. The new teams will usually contain no failed images. However, this cannot be guaranteed because an image might fail while executing the FORM TEAM statement. 4. Suggested edits In 11.6.9 FORM TEAM statement In p2 change "Successful execution of a FORM TEAM statement" to "Execution of a FORM TEAM statement that is successful or that assigns the value STAT_FAILED_IMAGE to the ". Delete p6.
