Hi,
I was getting this error message for one of my script.
The reason came out out to be, I had not place a semi-colon at the end of
try-catch block.
try {
something
} catch some_exception {
do something
}
After I placed the semi-colon, I am no longer getting this error (Can't use
string
something
}
After I placed the semi-colon, I am no longer getting this error (Can't use
string (1) as a HASH ref while strict refs)
try {
something
} catch some_exception {
do something
};
My questions is I have quite a few scripts that are using the SAME try-catch
block without
no longer getting this error (Can't use

That's exactly right. I meant that, if you were using an external file,
you only needed to replace the line

an array with its respective values? Unless, internally, Perl stores arrays

Hi all,
I have a script which takes a string of alphabetic characters as an argument,
generates all combinations of the characters and all permutations of the
combinations, then looks up each result in a list of valid words, if the result
is a valid word it gets stored in an array.

Hi Rob,
Thank you for your response, sorry it wasn't as clear as I thought it might
have been.
I have a script, and I want to feed it a special thing to let it know that
any character (A-Z or a-z does upper lower case matter?) is valid, but I
also want to use other characters at the same

so that only full words match, and I have used the i modifier for
case-insensitivity. If everything is in the same case, you can dispense with
the /i modifier for a little more efficiency; just lower-case your input
pattern first.

Hi Jim, thanks for replying :)
$word_list{$_} = 0;
If you assign 1 to the hash value, you can dispense with the 'exists' in
your test, below.
#Here, using a hash looks much cleaner than iterating through an array
push(@all_combinations, $temp_word) if (exists $word_list{$temp_word});

Hi Perl users, Quick question, I have a one long string with tab delimited

What is $gene_id? Are you by any chance using '$' at the beginning
of your search pattern instead of the end?
Why are you escaping the quote marks?
Why is there no space after 'gene_id'?
