using perl level 36 on a Sun 4/110 running SunOS 4.1:

I want to convert to lower case a string I have
matched. I want to do it in place (in $1);
I discover that I can't write to $1;
Is this a bug or a known/justified feature?

demonstrated by the following script.

#! /usr/local/bin/perl
$_='A';
m/(.*)/;
$1 =~ y/A-Z/a-z/;
print "I expect 'a'; I get '$1'\n";
$1='B';
print "I expect 'b'; I get '$1'\n";



        thanks
