Analysis of the code you attached.

The above line is pointless.
--- Agreed.
The next couple lines are great:
($year, $month, $mday, $hour, $minute, $second, $timezone) =
$quote_date = /^Rates as of (\d+).(\d+).(\d+)
($year, $month, $mday, $hour, $minute, $second, $timezone) =
/^Rates as of (\d+).(\d+).(\d+) (\d+):(\d+):(\d+) (\w+) (.*)$/;
The following code is pointless:
$year = $1;
$month = $2;
$mday = $3;
$hour = $4;
$minute = $5;
currency.csv contains using the code below. The date has been
adjusted from 2000-12-30 00:16:19 UTC to PST. The rest of the file is
still not being processed.

You seem to be misunderstanding one particular
aspect of perl. Given the following:
while (INFILE) {
# do something
The second loop is executing. The TEST statement worked.
This will surely print out, which shows that the regex
didn't match. In other words:
($cur_sym, $cur_desc, $usd_unit, $units_usd) =
/^([A-Z]{3})( [A-Za-z])+\s+(\d+\.\d+)\s+(\d+\.\d+)\s*$/;
Doesn't match:
USD United

Ok.
The Currency part of the email has a fixed format that is never
deviated from:
1-3 $cur_sym
4 space
5-32 $cur_desc
33-35 (3) spaces
36-55 d8.d10 (.00)
56-58 (3) spaces
59-78 d8.d10 (.00)
Got a combination that sort of works. It returns all the required
fields but truncates any line where $usd_unit or $units_usd has more
than 1 digit before the decimal point. There can be as many as (8)
digits before and (10) digits after the decimal point in both cases.
Here's the regex I'm

Here's the regex
1. I want to read in a text file and match any line that begins with
three capital letters followed by a space. i.e. USD
How do you do that?
2. I need to ignore any blank lines, lines containing all ---, lines
containing all ===.
Again, how?
Thanks in advance,
Jack

while () {
will read from the file(s) you specify on the command
line when you run your perl script, ie
perl myscript.pl

The special variable $| sets the autoflush. See PERLVAR documentation.
Whats this person does is a dirty way of setting $| to a true
value (not 0 or undef).
Default = 0.
why do you say 'dirty' ? .. do you just mean 'less readable' ? .. or are you
implying some other
