awk remove column with conditions?
Folks:

I have a file which has 3 columns. Using awk I want to remove rows from column 3 (Col3 <> A) where it is not equal to A. All columns are seperated by "|".

Col1|Col2|Col3|Col4
1 | 2 | A | 4
2 | 3 | A | 5
3 | 4 | B | 6
4 | 5 | A | 7
5 | 6 | B | 8
6 | 7 | A | 9

The output should be: I am newbie so I need the awk script which will give me this output so that I can automate the process.

Col1|Col2|Col3|Col4
3 | 4 | B | 6
5 | 6 | B | 8
