By looking through the PDL::MISC::IO code I found the syntax:
($val1, $val2, $val3, $name, $val3) = rgrep {sub} *IN,
{TYPES=>[double,double,double,byte,double]}
Note that I have to specify all of the column types or none, empty column masks
do not subsume the default type.
However, it still provides 0's for the string capture from the regexp.

Subject: RE: [Perldl] Using rgrep multiple times on the same file
What is the correct syntax for rgrep to specify character data in grep? The
following does not seem to work as it returns errors on every line as it
iterates through the file.
($val, $name, $val2) = rgrep {/^\s(\d+)\t(\w+)\t(\d+)$/, TYPES =>
[int,byte,int]} *IN
when I take out the TYPES:
($val, $name, $val2) = rgrep {/^\s(\d+)\t(\w+)\t(\d+)$/} *IN
Then when I query $name it will be a piddle of the correct dimensions of type
double with all values = 0.
Pointers on where I am going wrong? Thanks,

Subject: Re: [Perldl] Using rgrep multiple times on the same file
Thanks Craig, I just tried using the seek command and it works as well.
Is there a way to specify that one of the columns is a string/character type?
I am parsing data that looks like :
0 0 192 alpha 0 locked -------- 485 -38.75 34 205 0x00000fe5
Using rgrep to capture the first 4 fields and the 9th field. The data is
intermixed with other data in the file so I can't use rcols.
($a, $b, $c, $d, $e) = rgrep
{/^\s+(\d)\t(\d)\t(\d+)\t(\w+)\t\d\t\w+\s+w+\s+\d+\t(\-\d+\.\d+)\s+\d+\t\d+.*/}
*IN;
$d is a string and when I print the number of elements it is the same as the
other columns, however, I can't print any of the individual values, nor find
the uniq values.
The datatypes available doesn't have a character or string type, so I am not
sure how to change it so that I can read it.

I think you need to reopen the file.

Hi Folks, I am trying to use rgrep to pull out data from the same file that
occur in different areas of the file using rgrep. My first use of rgrep works
as expected, it is upon subsequent calls that I get nothing returned.
================================================================
Ex:
pdl> open IN, "< LAV800_BTS232_APR08_BETA-LAUBSC-20110428134127.txt"
pdl> ($rx0,$rx1) = rgrep {/^\t(\d+)\t(\d+)$/} *IN
pdl> p nelem $rx0
7760
pdl> p nelem $rx1
7760
pdl> $rx0=()
pdl> p nelem $rx0
1
pdl> p nelem $rx1
7760
pdl> ($rx0,$rx1) = rgrep {/^\t(\d+)\t(\d+)$/} *IN
pdl> p nelem $rx0
1
pdl> p nelem $rx1
1
================================================================
I am actually grepping different regexp but doing the same one seemed like the
most obvious way to show that it isn't working the second time it is called.
Any ideas? Thanks,
