Re^3: using constants in regex/search

That's identical to

    if ($input =~ /$NAME/) {...}

which is what I used, so I don't get your point.

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"; };` [download]	[reply] [d/l]

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]

You're thinking of `${NAME}`. `${\NAME}` is the scalar version of `@{[ NAME ]}`.	[reply] [d/l] [select]
