The OP had already posted code that utilized the format for print as specified in perldoc -f print

for my $x (0..1)  {

print { $marctags[$x] }  $tagdata[$x] ;

}

Then the OP stated:

use strict will raise a : Can't use string ("FOO") as a symbol ref while "strict refs" error that i don't know how to avoid here... So use FileHandle may be better :)

Your reply presented a change to the print statement which was working as last presented so I assumed (probably in error?) that you were replying to his error message.
