You do something in the BEGIN section, before the before.txt is processed.
And then you do nothing in the main section (where it's too late anyway).
The solution is to process the file in the main section and store it into variables (An array that is addressed by the $1 values), and then process/print in the END section. Like RudiC did.
The following is multi-line for readability (at least for me), and does not have the NR==FNR {...; next} overhead (that takes the first given file, where the following code will take the next file(s) - but here is only one file).
It prints with an explicit if - else, like you did; compare with RudiC's implicit if!

PPI::Statement::Scheduled(3) User Contributed Perl Documentation PPI::Statement::Scheduled(3)NAME
PPI::Statement::Scheduled - A scheduled code block
INHERITANCE
PPI::Statement::Scheduled
isa PPI::Statement::Sub
isa PPI::Statement
isa PPI::Node
isa PPI::Element
DESCRIPTION
A scheduled code block is one that is intended to be run at a specific time during the loading process.
There are five types of scheduled block:
BEGIN {
# Executes as soon as this block is fully defined
...
}
CHECK {
# Executes after overall compile-phase in reverse order
...
}
UNITCHECK {
# Executes after compile-phase of individual module in reverse order
...
}
INIT {
# Executes just before run-time
...
}
END {
# Executes as late as possible in reverse order
...
}
Technically these scheduled blocks are actually subroutines, and in fact may have 'sub' in front of them.
METHODS
type
The "type" method returns the type of scheduled block, which should always be one of 'BEGIN', 'CHECK', 'UNITCHECK', 'INIT' or 'END'.
TO DO
- Write unit tests for this package
