Are ALL pattern matching variables set back to undef once another m// or
s/// expression is encountered, even if it contains no parenthized
expressions?
For example, I would have expected $1 & $2 to be valid in BOTH print
statements below...
#!/usr/bin/perl -w
#
$string="ABC DEF GHI JKL MNO PQR STU";
if ($string =~ /(.{7})\s+(.{7})\s+/)
{
$p1 = $1;
$p2 = $2;
print ("1 = $1, 2 = $2, p1 = $p1, p2 = $p2\n");
$p1 =~ s/\s+//g;
print ("1 = $1, 2 = $2, p1 = $p1, p2 = $p2\n");
}
Thanks,
-Dan
