Why didn't you post that input file in your first message? And why didn't you tell us all your requirements at once? Because probably that doesn't involve an improvement in the code, but to redo it with other approach. Take it as an advice, but you will find more help if work like that.

Say the input file is the one below. I need to replace 1st P0 with M0 and second with 00 if and only if the value of port is 1 on both V{}
What does it mean? I don't see any 'port' value in your input file.

kaptain
KAPTAIN(1) General Commands Manual KAPTAIN(1)
NAME
kaptain - Universal graphical front-end for command-line programs.
SYNOPSIS
kaptain [options] file
DESCRIPTION
kaptain reads the given file and builds a user-friendly dialog according to the grammar rules found in it.
See info kaptain for a detailed overview.
OPTIONS
kaptain accepts the following options:
-h, --help
Show summary of options.
-V Run in verbose mode.
--version
Show version of program.
--test Run in test mode. This means that commands are not executed when a button is pressed, only printed to the standard output.
-V, --verbose
Report more information on processing the input file. Internal representation of the grammar and the dialog tree is also printed.
Use this flag if Kaptain does not work as expected.
-c <host:port>, --client <host:port>
Establish communication channel as a client connecting to a server on <host> listening on <port>.
-s <port>, --server <port>
Listen to the specified <port> and accept the first connection. This will be used as a communication channel.
-p <command>, --pipe <command>
Start the given command and communicate with it on its standard input and output. Don't forget to quote <command> if it contains
spaces or other metacharacters used by the shell.
--stdio
Use standard input and output for communication. In this case you must specify an input file, thus grammar script cannot be read
from the standard input when it is used as a communication channel.
--no-input
Instructs Kaptain not to process messages received on the input channel.
--no-output
If this flag is set, Kaptain will not send any messages on its output channel.
