try this

#!/usr/local/bin/perl
$var="Quantity_381_04032000101718.x";

($junk,$a,$b)=split(/_/,$var);
$b=~ s/\..*//g;

print $a," => ",$b,"\n";

or

($a, $b) = /(\d+)_(\d+)/;

and for the second example:

($a) = /_([\d_]+)/;

$_ = "Quantity_381_04032000101718.x";
($a, $b) = /(\d+)_(\d+)/;
print "$a\n$b\n";

($a) = /_([\d_]+)/;
print "$a\n";

--------------------
Output:
381
04032000101718
381_04032000101718

Which is what you said you wanted.
