I found a couple of problems in my rcols format and the regexp and have
corrected that so that rcols responds without error. I missed that the INCLUDE
is just the filter and had the listed the columns as per the groupings, and I
had forgotten the PERLCOL in the column identifiers.
($val1, $val2, $val3, $name, $val4) = rcols ('filename.txt' ,\
0,1,2,3,8, {
INCLUDE=>'/^\s+\d\t\d\t\d+\t\w+\t\d\t\w+\s+\w+\s+\d+\t\-\d+\.\d+\s+\d+\t\d+\t0x[0-f]+$/',\
PERLCOLS => [ 3 ]})
It does capture all of the numeric data. I still can't get the name though. Do
I have to specify that the PERLCOL is a string somehow?
Thanks,

Thanks Doug, I was hopeful as I hadn't thought of doing that before.
Unfortunately I get the following error.
Runtime error: Can't use an undefined value as an ARRAY reference at
c:/Perl/site/lib/PDL/IO/Misc.pm line 664.
For the command:
($val1, $val2, $val3, $val4, $name) = rcols ('filename.txt' , 0,1,2,4, {
INCLUDE=>'/^\s+(\d)\t(\d)\t(\d+)\t(\w+)\t\d\t\w+\s+w+\s+\d+\t(\-\d+\.\d+)\s+\d+\t\d+0x[0-9A-F]+$/',
PERLCOLS => [ 3 ]})
I thought that it would treat the $name as the last populated item as a PERLCOL
with it being the 4th item in the regexp.

Cliff,
Can you use the INCLUDE or EXCLUDE options of rcols to filter out the unwanted
lines (e.g. use something like
INCLUDE=>'/^\s+(\d)\t(\d)\t(\d+)\t(\w+)\t\d\t\w+\s+w+\s+\d+\t(\-\d+\.\d+)\s+\d+\t\d+.*/'
), or am I just being dense and this is a spectacularly-stupid idea ;-)
I was also going to suggest doing a "pre-filter" stage, whereby you read in the
file and filter out all the unwanted lines before using rcols or rgrep, but
then I remembered that my perl-fu has all leaked away and I can't remember if
you can treat a string as a filehandle (as I think rcols/rgrep require); I'm
sure there's away but I don't know it off hand.
Doug
