I may be wrong, but in the code you suggest,

Code:

{print $0,A[$2,$5]}

it looks like that will print all of File2 (i.e., the entire line) prior to the matched output.

Perhaps

Code:

{print $1,A[$2,$5]}

does the trick.

Sorry about that. I didn't look closely enough at your output spec after noticing the wrong fields being used as indexes into your A[] array. If we go back to your 1st post in this thread, you said:

Quote:

If $2 and $5 of File2 match $1 and $2 of File1, I would like to print $4 of File2 followed by $0 of File1.

so instead of:

Code:

{print $1,A[$2,$5]}

it would seem that you might need:

Code:

{print $4,A[$2,$5]}

And, of course, you still need the condition on that action:

Code:

($2,$5) in A{print $4,A[$2,$5]}
