Summary 0001821: Define the values of $0, $1, etc. in the END section
Description The value of NF, i.e. the number of fields read, in the END section is defined in the standard as:
Inside an END action, NF shall retain the value it had for the last record read
but the value of $0, $1, and the other fields is not defined. Most modern awks will have them retain the value of the last record read, just like NF, but it is currently undefined behavior which seems like it's a simple omission from the spec.
Desired Action Update the spec to say:
Inside an END action, $0, $1, and the other fields shall retain the values they had for the last record read
Tags No tags attached.

The suggested wording doesn't work for the NF=0 case. It needs to be something more like:
Inside an END action, $0 and, if NF is greater than 0, the fields $1 through $NF shall retain the values they had for the last record read.
