Hi guys:
I'm a linux enthusiast who is trying to get stuck into Perl.
Currently I'm trying to put together a script which will handle text
files.
I'm having problems with one line which is trying to ascertain the
position of ascii 2-digit numbers in a string.
I've used the following line --
if (($x = index($job{Ra}, /[0-90-9]/,0)) != -1)
-- in which $x keeps on being assigned 0 instead of 4.
The content of $job{Ra} is: "Ra: 45k"
I've fairly sure that I'm correct on the REGEXP syntax of /[0-90-9]/
which is looking for 2 consecutive numbers in the string. I've checked
the REGEXP syntax with lines like --
if ($job{Ra} =~ /[0-90-9]/)
-- which are evaluated as True.
What's going wrong in the index function above? I should be able to use
a REGEXP for the SUBSTR in the INDEX function shouldn't I?
BTW, in case I can do this a better way, what I am trying to do is
extract any numbers in this string. May be 0, 1 or 2 numbers. Then
compare the number(s) with a "reference" number.
