[ILUG] awk question

[Brian Foster]

 I haven't following this very closely, but my understanding
 is the gawk(1) script in question is basically:

     /RE₁/ { x = $1;     }
     /RE₂/ { y = $3;     }
           { print x, y; }

 and the “problem‟ is apparent-duplicate lines are printed.

 well, what else do you expect the script to do?
 of course it will print an output line for every input line;
 the 3rd ACTION (the last one, with no PATTERN) matches every
 input, so the last-assigned values-to-print («x» and «y» in
 my example above) are printed as the output.

 the solution?  below, I am assuming nothing is to be printed
 until all of the values-to-print have been set, and then the
 cycle repeats.  this is _not_ robust, yer kiloage will vary!:

     BEGIN      {              state = 0; }
     /RE₁/      { x = $1;      state++;   }
     /RE₂/      { y = $3;      state++;   }
     state == 2 { print x, y;  state = 0; }

 this may not quite what is wanted, but is --- possibly ---
 close to what is intended?

cheers!
