Hi,

Sorry if I misunderstood what you were asking earlier.

1. I have read the documentation for join, and as far as I can tell, I'm doing it properly. I have tried changing the double quotes to single quotes but that actually made printed \t instead of the tabs themselves

2. The printflush method comes from http://perldoc.perl.org/IO/Handle.html, which states that "$io->printflush ( ARGS ) Turns on autoflush, print ARGS and then restores the autoflush status of the IO::Handle object. Returns the return value from print."

However, this doesn't make any difference to my output from when I just use print:

my $printing = join("\t",@arrayToPrint); $normal_fh->print("$printing\n");

Thanks for your help, I will update with any progress.

    Thank you for the clarification.

    But you never showed us parts of your code -- the hashbang, if any, and the use IO::Handle;. That would have forestalled my concern about the appearance of printflush without a predicate. Discipulus sussed that out, but obviously, I didn't... and, in any case, we often see problems such as using a function from a module without useing the module. Those cases make it very hard to help if the code presented isn't an exact copy of the code which generated anomalies or errors.

    BTW, the preceding para may have some value for you but I hope it also provides some benefit for future newcomers who stumble upon it.

    And, as has already been said, welcome to PM.
