To: J3 07-255r2 From: Bill Long and John Reid Subject: UTI 120 (p213): Initial values of co-arrays Date: 2007 August 8 References: J3/07-007r2 (N1678) Discussion NOTE 8.33 says that there may be a need for a SYNC ALL statement before the first executable statement of the main program. The editor takes the view that this is not necessary since the standard says that an initialized variable is initially defined (that is, before its own image or any other image accesses it). However, the text in 2.4.5 is currently unclear regarding the beginning of execution. An edit is provided to clarify the sequence of actions. Edits to 07-007r2: [27:9] In 2.4.5 Execution sequence, replace the first sentence with "Following the creation of a fixed number of instances of the program, execution begins on each image." [213:18+] In 8.5.2 SYNC ALL statement, delete NOTE 8.33.
