[PLUG] gawk: a pattern that separates two similar strings

[Rich Shepard]

I've downloaded a data file where the permit type can be Active, Inactive,
or Draft.

Removing all Draft records was easy. Removing all Inactive records has so
far escaped my gawk (and LO Calc) efforts because Inactive contains the
substring 'active'.

My script:
BEGIN { FS = OFS = "," }
  NR ~ /1/ { print $0 }
  $4 == "Inactive" { next }
  $4 == "Active" { print $0 }

I've also tried with matching:
  $4 ~ /Inactive/ { next }
  $4 ~ /Active/ { print $0 }

And, of course, specifying only field 4 containing Active also fails.

My AWK books and web searches haven't taught me how to write a pattern that
matches only 'active' and not 'inactive.'

Would the substr() function do the job? E.g,, substr(Active,1,6)

Here are two sample records:
410 Auto Wrecking,410 Auto Wrecking,So3011780,Inactive,Industrial SW GP,27865 
Sr 410 E,Buckley,Pierce,98321
410 Auto Wrecking,410 Auto Wrecking,WAR011780,Active,Industrial SW GP,27865 Sr 
410 E,Buckley,Pierce,98321

TIA,
