hello, I have a problem with the parameter passing mechanism among 2 subroutines. my code is as follows.

I have 2 subroutines. the first one takes 2 parameters from command line:
* text file name containing file list
* file format

then it reads the given file, and fetches individual file names (with full path).

then it passes a file path and format to second subroutine called test_format. but these parameters becomes "unreadable" from the array object containing parameters, when I try to convert this array to an hash object (args2hash). because when I print the array object, it gives this output.

"/abc/def/xyz.dat format dat"

Actually it should be like this:

"input /abc/def/xyz.dat format dat"

The "input" keyword is missing.

What should I do?

sub test_filelist_format {
    my $obj = shift;
    my $args = Parser::args2hash (@_);
    
    my $input = $args->{'input'};
    my $format =  $args->{'format'};

    if (!$input || !$format) {
    die("input file or format missing!\n");
    }
    
    ## if not list readable, return -1
    if ( $obj->is_readable(file=>$input) < 0 ) {return -1}

    ...

    my $formatstatus = test_format ("input" => $line, "format" => $for
+mat); 

    ...

}

sub test_format {

    my $obj = shift;
    my $args = Parser::args2hash (@_);

    my $input = $args->{'input'};
    my $format =  $args->{'format'};
    my $gzip = $args->{'gzip'};
    my $columns = $args->{'columns'};

    if (!$input || !$format) {
    die("input file or format missing!\n");
    }

    if ( $obj->is_readable(file=>$input) < 0 ) {return -1};

    ...
}
