07-267R1 To: J3 From: Dick Hendrickson Subject: Interpretation: Blanks as separators in namelist input Date: 2007 August 7 NUMBER: F03/0097 TITLE: Blanks as separators in NAMELIST input KEYWORDS: Namelist input, blanks, separators DEFECT TYPE: Erratum STATUS: J3 consideration in progress QUESTION: 1) Was in intended that blanks be allowed as separators in Namelist Input? Consider a namelist input fragment: I = 3 J = 4 Page 243:5 says that namelist value separators are the same as list directed value separators. Page 239:7 says those value separators are "...blanks between values" and then defines what the values are. The "J" above isn't a value, so the blanks aren't separators and the fragment is illegal for namelist input 2) Is there a similar problem with namelist comments as in this fragment? I = 3 ! this is a namelist comment ANSWER: 1) Yes, it was intended to allow blanks as separators for namelist input. Edits are supplied to correct the wording in the standard 2) Yes, there is a similar problem with comments. The fragment is intended to be legal. The edits correct the error. EDITS: [243:5] Replace the paragraph by "A value separator for list-directed formatting (10.9) is also a value separator for namelist formatting. In addition, one or more contiguous blanks between the a nonblank value and a following object designator or "!" comment initiator is a value separator."
