i found this article:
http://www.support4omega.co.uk/PSQL_Scripting/index.html

It's about 'Accessing Pervasive.SQL With Perl'


Below is one simple example on how it works:
use strict;
use warnings;
use 5.010;
use Win32::API;

# old parameter format
my $funchandle = new Win32::API("w3btrv7.dll", "BTRCALL", "IPPPPCc", "I");

if (defined $funchandle)
{
say "funchandle set";
my $operation = 26; # get version information
my $posBlock = " " x 128;
my $dataBuffer = " " x 255; # maximum buffer size is 255 bytes
my $dataLength = 15; # ...we need to specify >= 15 bytes to
get full version info
my $keyBuffer = " " x 255; # actually no need to set key buffer info
for this example...
my $keyLength = 255; # ...because none of it is used
my $keyNumber = 0;

say "Calling function...";
my $return = $funchandle->Call($operation, $posBlock, $dataBuffer, $dataLength, $keyBuffer, $keyLength, $keyNumber);

say "return = $return";
say "data buffer = $dataBuffer";

my($version1, $revision1, $type1, $version2, $revision2, $type2,
$version3, $revision3, $type3) = unpack('SSCSSCSSC', $dataBuffer);

say "Client: version = $version1, revision = $revision1, type =
$type1 (".chr($type1).")";
say "Workgroup engine: version = $version2, revision = $revision2,
type = $type2 (".chr($type2).")";
say "Server engine: version = $version3, revision = $revision3, type
= $type3 (".chr($type3).")";
}
else
{
say "funchandle not set";
}
