$port->are_match("8");# possible end strings
The $c string should then contain characters except for the
number 8 which would be the end of that string.
I have tried it with and without an are_match pattern and
it just roars along, looping endlessly at the lookfo
read any answers there but this has
been a strange issue as I never really found out why the list
stopped.

coincides with the year I retired from work and I haven't needed
to post until recently.
Many thanks.

I put the digit '8' in the are_match expression and now,
when I run the perl application, I see
0 1 2 3 4 5 6 7 so it is breaking the string on 8 which is
precisely what I need for the test to work.
Now I can go on and do something useful. I was being
dense,

Thank you.

That is exactly what it was. This was as easy as falling off the

n running perl -d to view the
contents of the string to make sure it is what it should be?

Someone brought to my attention that I had failed to define a
couple of variables in the sample code I posted and they were
quite right. I don't mind sharing my work but the entire
application I wrote to get a brief local weather summary is
242 lines and I was trying to stay close to the topic, he
has a
few more lines and the data dumper is commented out but it
demonstrates what is happening.
If there is some way to see what Time::Piece thinks I am
trying to tell it to do then one might be able to figure out what
is wrong but a miss is the same as close so I can't tell if I am
g
("$obtime[1], %d %b %Y %H:%M:%S %z");
Still the parse error.
Right now, I do have both
use Time::Local;
use Time::Piece;
in the program and Time::Piece is supposed to replace many of the
functions of Time::Local. If I comment out Time::Local, a
reference to gntime breaks.
g
arguments you saw. I figured the %D issue out but, by that time,
I had messed around with things long enough that I forgot the ,
which separates the two arguments to that method must not be part
of the quoted string so even when the %variables were right, the
call would never work the way I had it.

Before I take this too far, I want to make sure I am not
doing something wrong with use of the Device::SerialPort module
in perl.
The code below talks to what it thinks is a RS-232 serial
port and controlls a radio scanner so that one can program the
scanner's settings and enter fr
=~ $regextest) {print "yes\n"; }
I got a yes that time but that's not good enough.
I'll probably kick myself when I find out what I am missing, but
I can't seem to get this to work.
Thank you.

First, thank you but read on, please.
I couldn't agree more. That should do it but when I
don't escape them, I

Uri Guttman writes:

Now that I know how this works, I will probably change to
{4,} as this would match 4 or more digits. From reading the
documentation, {4} means 4 and only 4. {4,6} means 4 but nothing
else except 6. {N,}
gic and
bitwise operators plus a much more easy-to-use string handling
capability which is why I am asking this question.
I may be looking in the wrong places but, so far, I seem
to be batting zeros when looking for perl and alsa together.
Any good ideas are greatly appreciated, here.

Many thanks. I am glad I asked the question but it has taken me
cought up with me or I am missing something about the
upgrade process that only broke perl as far as I know.
Thanks for any constructive ideas for getting perl back.

ecause there has not been
one bit copied using either of the two modules I tried and the
dircopy module does exactly what one needs in this particular
case but silently fails 100% of the time.
Thanks for any good ideas since this appears to be quite useful
but hasn't shown that side of it
Many thanks to all 3 who replied. You've given me more things to
try. For one brief shining moment, I thought the very first
suggestion had fixed the problem but I neglected to put the
"or die!;" clause at the end of the line and it's still the same
silent failure.
For now, I will use t
that reads the sound
and stores it in files.
Many thanks.
