`$string = eval { $_ };` [download] Presuming $_ is not tied in such a way that it would trigger code that "die"-ed, your snippet is the same as: `$string = $_;` [download] -- Randal L. Schwartz, Perl hacker Be sure to read my standard disclaimer if this is a reply.	[reply] [d/l] [select]

It looks like you are confusing the "string form" of eval with the "block form". Try `perldoc -f eval` to get the full story, and then merlyn's comment may be clearer. To do what you want to do, you need something like `$string = eval qq("$_");` [download] where $_ contains your 'test_string_$val'. But as Roy already pointed out, this may not be a very wise thing to do in the first place. the lowliest monk	[reply] [d/l] [select]
