in reply to Re: Interpolation in a hash key
in thread Interpolation in a hash key

Right, the bits in HERE docs, work fine as shown:
print<<"CONNECTION2";
<td width="78" align="center" valign="middle">$$hashRecordPtr{"connect
+ion2_size$count"}</td>
CONNECTION2

But its just these bits now:(just a standard double quoted print statement)
print "<td width=\"78\" align=\"center\" valign=\"middle\">$$hashRecordPtr{'part_number1'}</td>"; Any ideas on this last bit?

Nearly there, thanks guys.

    So, in this last case, you've got a double-quoted string with a single-quoted substring. Interpolation rules indicate that a variable name inside the overall double-quoted string will still be resolved, so this should work (although it makes me nervous with all those backslashed double-quote characters):

    print "<td width=\"78\" align=\"center\" valign=\"middle\">$$hashRecor
+dPtr{'part_number${count}'}</td>";

    Of course, I could be wrong -- you should try it out. :) When in doubt, I use the curly braces, because I think it makes it more readable and it has saved my bacon once or twice.

      This doesn't work ptum, at least not for me
      I'll just put it in a HERE doc for now until I figure it out.

        Make life easy for yourself. Use qq() instead of your outer double quotes.

        my $hashRecordPtr = { part_number1 => 1 };
my $count = 1;

print qq(<td width="78" align="center" valign="middle">$$hashRecordPtr
+{"part_number${count}"}</td>);
