I cannot get rescue to work

[Xeno Campanoli]

The example on page 108 of pickaxe gives me the following syntax error, for
instance:

../try4.rb:11: syntax error
rescue SystemCallError
^
xeno@linux:~/study/data>

Presumably there is something simple I'm doing wrong. Please make a
suggestion, as I'm really stuck.

Can you post the whole file, or at least the context in which this
statement is used?
Kinda hard to catch syntax errors without the code.

Check your typing, you may have missed ), or end, or begin. Paste the
whole exercise, otherwise it is impossible to pin-point the problem.

Sorry, I tried to say before, I figured it out. It turns out you have
to put the rescue segment
on the bottom of the block, apparently, and I made it work when I did
that. I was however
fooled by the raise statement I left in afterwards. In taking out the
raise, and putting in
my own diagnostics, I now have mostly what I want, though it would be
nicer to get a line
number or statement indicator at the rescue point. For now I'm just
assigning the line to a
global to keep it around. If anyone can make a suggestion on that, it
would also be helpful.

Thanks to the several people who have helped me on this.

Sincerely,

Xeno

If you want to know where the exception was originated from, you can
use Exception#backtrace method. With a little bit of parsing, you will
get a line number and a method name.

Thank you. I will try using that in my next draft. I'm trying to
finish one last piece of the first before I get horizontal tonight.
