Hi. I'm new to awk and have searched for a solution to my problem, but haven't found the right answer yet. I have two files that look like this:

file1
Delete,3105551234
Delete,3105551236
Delete,5625559876
Delete,5625556789
Delete,5625553456
Delete,5625551234
Delete,5625556956
Delete,5625556643
Delete,6265552486
Delete,6265559365
Add,7755559833

I would like to look at file1 and any entry that has "Delete" in $1, look for $2 (from file1) in file2. Then, create a third file, file3, with "D,"$1 of file2. So, the output with the above examples would look like this:

file3
D,93
D,110
D,114
D,118
D,125
D,127
D,129
D,133
D,134
D,137

I hope I'm making sense. Any help would be appreciated. Thanks.
