I get error in such simple test with two variables:

$ echo test|awk '$2 != ""? o="ABC" r="123" : o="123 r="ABC"ENDprint "o:"o" r:"r'
awk: cmd. line:1: $2 != ""? o="ABC" r="123" : o="123 r="ABC"ENDprint "o:"o" r:"r
awk: cmd. line:1: ^ syntax error
awk: cmd. line:1: $2 != ""? o="ABC" r="123" : o="123 r="ABC"ENDprint "o:"o" r:"r
awk: cmd. line:1: ^ syntax error
awk: cmd. line:1: $2 != ""? o="ABC" r="123" : o="123 r="ABC"ENDprint "o:"o" r:"r
awk: cmd. line:1: ^ unterminated string
$

with single variables it works fine:

$ echo test|awk '$1 != ""? o="ABC" : o="123"ENDprint "o:"o'
o:ABC
$ echo test|awk '$2 != ""? o="ABC" : o="123"ENDprint "o:"o'
o:123

You can't really do that with the ? : operator, since it can handle a single value only, and two assignments would generate two values.

Use an actual if statement instead:

$ echo test|awk ' if ($2 != "") o="ABC"; r="123" else o="123"; r="ABC" END print "o:"o" r:"r'
o:123 r:ABC
