Re^4: using constants in regex/search

You have copied the NAME value to a variable and used as $NAME.
i have specified a method, which will use the constant NAME itself in the regular expression

use strict;

use constant NAME => 'abc';

if ($ARGV[0] =~ /${\NAME}/) { print "match"; };

You're sure you didn't update your post? I know about the difference between ${NAME} and ${\NAME}, and when replying, I checked to make sure there wasn't a \ there.	[reply]

i am updated my post Still you can access constant 'abc' in regular expression like ${NAME} without "use strict". While using the "use strict", this needs to be escaped. "use strict" is important.	[reply]
