Re^2: File handle as a input variable

I tried that. But it does not work with use strict I get an error : Can't use string ("File_Handle") as a symbol ref while "strict refs" in use at Log_Preocessing.pl line 28. use strict; my $Sample = "C:\\Perl\\Ref.txt"; my $File_Handle = "File_Handle"; open $File_Handle, ">$Sample" or die "Cannot open $Sample.txt for read :$!"; print $File_Handle "hi"; while (<$File_Handle>) { }

Do it exactly the way Marshall shows and it will work. The reason you are getting that error is because `$File_Handle` is not an "undefined scalar variable"". So instead of setting it beforehand to "File_Handle", declare it and set it in the call to open: `open my $File_Handle`. See open for more information on this.	[reply] [d/l] [select]

This: my $File_Handle = "File_Handle"; is wrong. delete that. for the open, put a valid path in there, like: open my $File_Handle, ">", "full_textual_path_to_a_file" or die .... Later use: print $File_Handle "some stuff\n";	[reply]
