Hi Rob,
Many thanks. That does what I want :) Now I need to study your code to learn
why.

The modern way to open a file is to:
1) Use the three argument form of open().
2) Create a variable for the file handle.
open (my $BHF_FILE, '<', '/home/bob/tmp/md4music');
You should *always* verify that the file was opened correct
Why are you replying to me? My post did use the three-argument form of
open(). Also:
- It is bad form to use upper case letters for lexical variables

Hi Bob
I suggest you forget about regular expressions and use the library
function split() instead. Take a look at the code below.
HTH,

Thanks. There's a lot in your version for a newbie to learn, but
unfortunately, it still gives the same error :(
It helps if you post the actual code generating the error. You should
also trim the accumulated text to remove non-relevant portions.

Hi,
I am trying to split the lines in a file into two halves (at the first
space) each half going into an array. The code I have written is below. The
print command is there to test that things worked correctly, but it only
gives an error for each instance of the print command...
