Hi,
I have some issue with the code of mine.
I see a strange behavior.
The pattern matching doesn't work correctly when my syntax is still perfect.
It matches irrelevant characters.

The problem goes like this:

The patterns are of the form ALLOCID_0xABCD.
I need to match this and i send the exact data [$argument here]to be matched.

When i run my code, i find something of the pattern "xyzbnbb.c" also to get match.

Below is the code,

&match_routine($prev_file,@ids);

sub match_routine {
open(FH,"$dir_path/$prev_file");
open(FW,">$dir_path/$prev_file.swp");
print " The file is $prev_file and the ids are @ids";

while ($line = <FH>) {
#print FW $line;
foreach $argument (@ids) {

print "argument is $argument";
if ( $line =~ m/$argument/i ) {
print "content matched is $&\n argument sent is $agument\n";

}
}
}
close (FH);
close (FW);
}
Note the contents:

@ids=ALLOCID_0XABCD and so on.
$prev_file=abcd.cxx and similar files.

My aim is to open the file, match the pattern, and write something to the file.
Please find the output below.
Kindly check the lines print "argument is $argument" and "print "content matched is $&\n argument sent is $agument\n";"
"
argument is ALLOCID_0x0503
content matched is ALLOCID_0x0503
argument sent is
.............
.......
......

argument is ALLOCID_0x0503
argument is ALLOCID_0x0504
content matched is ALLOCID_0x0504
argument sent is



I get output for the first one, yet the next print shows nothing.
How could this be so? Immediately after passing thro' a pattern check, how could a value vanish away?
Can somebody explain me where i'm going wrong.

This line:

Needs to be checked. The first print is passing $&. The second is $agument. You've misspelled the variable name.

Thanks,i corrected that.
Yet please note that it matches irrelevant characters and again it is blank in the second output. I find it weird yet it happens.
The output is as below.

argument is ALLOCID_0x0604
argument is
content matched is ScannedMediaSimplexCount.c
