Summary: The impact of changing NR and/or FNR should be
defined
Description:
In most, if not all, modern awks a user can change the value of NR and/or
FNR and when the next record is read NR/FNR is incremented from the value
the user set it to rather than from the value it previously had:
$ seq 3 | awk 'NR==2{NR=7; FNR=23} {print NR, FNR, $0}'
1 1 1
7 23 2
8 24 3
but that behavior is currently not defined by POSIX.
Desired Action:
Add statements to the spec like:
---
Assigning NR a whole number shall set NR to that value from that point on
for processing of the current record and NR shall be incremented starting
with that value for all subsequent records read. Assigning NR any other
value is undefined behavior.
-
Assigning FNR a whole number shall set FNR to that value from that point on
for processing of the current record and NR shall be incremented starting
with that value for all subsequent records read. Assigning NR any other
value is undefined behavior.
