[Solved] Multiple line search, replace second line, using awk or sed

All, I appreciate any help you can offer here as this is well beyond my grasp of awk/sed...

I have an input file similar to:

Code:
&LOG
&LOG Part: "@DB/TC10000021855/--F"
&LOG 
&LOG
&LOG Part: "@DB/TC10000021852/--F"
&LOG Cloning_Action: RETAIN
&LOG Part: "@DB/TCCP000010713/--A"
&LOG
&LOG Part: "@DB/TC10000024401/--E"
&LOG Cloning_Action: DEFAULT_DISP Naming_Technique: DEFAULT_NAMING Clone_Name: "@DB/TC42500004692/--A"
&LOG Container: user
&LOG Part_Type: object
&LOG Part_Name: "object-name"
&LOG Part_Description: "object-desc"

What I need to do is replace any instances of the following:

Code:
&LOG Part: "@DB/TCCP000010713/--A"
&LOG

with the following:

Code:
&LOG Part: "@DB/TCCP000010713/--A"
&LOG Cloning_Action: RETAIN

In pseudo code terms...

If a whole line matches: &LOG Part: "@DB/TCxxxxxxxxxxx/xxx" (where the "x"s could be any character)
and the next whole line matches: &LOG
replace the "next line" (&LOG) with: &LOG Cloning_Action: RETAIN

Note there may be multiple instances needing replacement within a given file as the sample used here indicates

When run properly the above input would come out looking like (the change is highlighted in red):

Code:
&LOG
&LOG Part: "@DB/TC10000021855/--F"
&LOG Cloning_Action: RETAIN
&LOG
&LOG Part: "@DB/TC10000021852/--F"
&LOG Cloning_Action: RETAIN
&LOG Part: "@DB/TCCP000010713/--A"
&LOG Cloning_Action: RETAIN
&LOG Part: "@DB/TC10000024401/--E"
&LOG Cloning_Action: DEFAULT_DISP Naming_Technique: DEFAULT_NAMING Clone_Name: "@DB/TC42500004692/--A"
&LOG Container: user
&LOG Part_Type: object
&LOG Part_Name: "object-name"
&LOG Part_Description: "object-desc"

Thanks in advance for any help you can offer...

NAME
pyp - The Pyed Piper: A Modern Python Alternative to awk, sed and Other Unix Text Manipulation Utilities SYNOPSIS
pyp [options] files ... DESCRIPTION
pyp, the Pyed Piper, is a command line tool for text manipulation. It is similar to awk and sed in functionality, but its subcommands are Python based, and thus more familiar to many programmers. It can operate both on a per-line base and on the complete input stream. Different features can be pipelined in a single command by using the pipe character familiar from shell commands. pyp backs up its input for reruns with modified commands, and can save commands as macros. On the downside, the rerun feature makes it unsuitable for continuous pipe operation. OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. For a complete description, use --manual. -h, --help Show this help message and exit. -m, --manual Prints out extended help. -l, --macro_list Lists all available macros. -s MACRO_SAVE_NAME, --macro_save=MACRO_SAVE_NAME Saves current command as macro. use "#" for adding comments EXAMPLE: pyp -s "great_macro # prints first letter" "p[1]". -f MACRO_FIND_NAME, --macro_find=MACRO_FIND_NAME Searches for macros with keyword or user name. -d MACRO_DELETE_NAME, --macro_delete=MACRO_DELETE_NAME Deletes specified public macro. -g, --macro_group Specify group macros for save and delete; default is user. -t TEXT_FILE, --text_file=TEXT_FILE Specify text file to load. For advanced users, you should typically cat a file into pyp. -x, --execute Execute all commands. -c, --turn_off_color Prints raw, uncolored output. -u, --unmodified_config Prints out generic PypCustom.py config file. -b BLANK_INPUTS, --blank_inputs=BLANK_INPUTS Generate this number of blank input lines; useful for generating numbered lists with variable 'n'. -n, --no_input Use with command that generates output with no input; same as --dummy_input 1. -k, --keep_false Print blank lines for lines that test as False. default is to filter out False lines from the output. -r, --rerun Rerun based on automatically cached data from the last run. Use this after executing "pyp", pasting input into the shell, and hitting CTRL-D. SEE ALSO
