Dear monks, I am new to perl and I am currently trying to format a file and print this out to a new file. This is the current code I have. 
#!/usr/bin/perl -w
open (my $SELECT.DAT2, '<', $ARGV[0]) || die "cannot open for reading,
+ $ ! "; 
open (my $OUT, '>', $ARGV[0]) || die "cannot open for writing, $ ! "; 
printf $OUT "NO" "\n", " 'SOURCE' ", "SEC", "Q", "SEC", "\n", "LONG", 
+"LAT", "DEPTH", "GAP";
close ($SELECT.DAT2);
close ($OUT);

Every time I try to run this code I get a syntax error at my. Does the file type matter when using the open command? I understand my code probably has more errors but a little help getting past this first error would be greatly appreciated.
