• #157 : Rank-agnostic array element and section denotation (https://j3-fortran.org/doc/year/20/20-113.txt, https://j3-fortran.org/doc/year/20/20-115.txt)
• #158 : TYPEOF and CLASSOF (https://j3-fortran.org/doc/year/20/20-114.txt)
• #1 : Namespace for modules (https://j3-fortran.org/doc/year/20/20-108.txt)
• Interpretation: FORM TEAM and failed images (https://j3-fortran.org/doc/year/20/20-102r1.txt)
• Interpretation: Collective subroutines and STAT= (https://j3-fortran.org/doc/year/20/20-104r1.txt)

Thursday 2/27

• Interpretation: events that cause variables to become undefined (https://j3-fortran.org/doc/year/20/20-119.txt)
• Edits for SIMPLE procedures (https://j3-fortran.org/doc/year/20/20-116.txt)

• #146 : Interpretation: allocatable component finalization (https://j3-fortran.org/doc/year/20/20-117.txt)

Friday 2/28

• #157 : Rank-agnostic syntax (https://j3-fortran.org/doc/year/20/20-120.txt). Passed unanimously with minor changes.
• #156 : Protected components (https://j3-fortran.org/doc/year/20/20-121.txt). Withdrawn to address conflicting interests.
• #160 : Edits for auto-allocate characters (https://j3-fortran.org/doc/year/20/20-122.txt). Passed unanimously with minor changes.
• Edits for procedure pointer association (https://j3-fortran.org/doc/year/20/20-123.txt). Passed unanimously.
• #157 : Edits for rank-agnostic bounds (https://j3-fortran.org/doc/year/20/20-124.txt). Withdrawn because some edits were missing and need to be added. There were concerns about fitting into the framework of generics later on.
• #157 : Edits for rank-agnostic array element and section denotation (https://j3-fortran.org/doc/year/20/20-125.txt). Failed (5 v 7). Missing edits, and disagreement on types vs rank-1 integers, the options need to be explored more.

• Interpretation: Public namelist and private variable (https://j3-fortran.org/doc/year/20/20-127.txt). Straw vote (0 yes, 8 no, 9 undecided). Passed unanimously with “no” alternative.
• Interpretation F18/015 (https://j3-fortran.org/doc/year/20/20-105.txt). Passed unanimously.
