<p>Thank you for the quick response.</p>
<p>From [doc://perlopentut#Pipe-Opens]:</p>
<blockquote>
"If you would like to open a bidirectional pipe, the IPC::Open2 library will handle this for you."
</blockquote>
<p>From [doc://perlipc#Bidirectional-Communication-with-Another-Process]:</p>
<blockquote>
"While this works reasonably well for unidirectional communication, what about bidirectional communication? The obvious thing you'd like to do doesn't actually work:"
<code>
open(PROG_FOR_READING_AND_WRITING, "| some program |")
</code>
"and if you forget to use the use warnings pragma or the -w flag, then you'll miss out entirely on the diagnostic message:"
<code>
Can't do bidirectional pipe at -e line 1.
</code>
</blockquote>
<p>Am I misinterpreting what that says? I may need to take a step back and revisit this in a bit to get a clearer perspective.</p>
