AWK: combining consecutive values in a field

Hi,

Here is my sample input

X 2 AAA
Y 3 BBB
Y 2 CCC
Z 4 DDD
In field 1, if the value of one line is same as that of next line, I want to concatenate the corresponding value of the second line in the third field with the value of the third field of first line. And I dont need the third line in the out put. phew!

Needed Output

X 2 AAA
Y 3 BBB_CCC
Z 4 DDD
I am a biologist and have no Idea regarding awk scripting. So please dont ask me what I have tried Smilie

Thank you very much in advance.

NAME
dbs_dumptabdata - Creates file set with SQL table data DESCRIPTION
dbs_dumptabdata is an utility to create a file set with SQL table data. For each table in the database dbs_dumptabdata calls the appropri- ate dumper utility with the output directed to a file named table.sql in the current directory. dbs_dumptabdata asks for a password if nec- essary. COMMAND LINE PARAMETERS
Required command line parameters are the DBI driver ("Pg" for Postgres or "mysql" for MySQL) and the database name. The third parameter is optionally and specifies the database user and/or the host where the database resides ("racke", "racke@linuxia.de" or "@linuxia.de"). COMMAND LINE OPTIONS
-t TABLE[,TABLE,...], --tables=TABLE[,TABLE,...] Comma-separated list of tables to dump. --exclude-matching-tables=REGEXP Excludes any table matching the regular expression REGEXP from dumping. --use-printtab Uses generic dump (similar to "dbs_printtab") instead of the dumper utility provided by the DBMS. BUGS
msql is not supported. AUTHOR
