Inside a double-quoted string, put a back-slash in front of "$" to get a literal dollar-sign: `print "A sample dollar amount: \$12.34\n";` [download] Or, simply use single-quotes, and don't use a back-slash: `print 'Another dollar amount: $56.78', "\n";` [download] Or use the `q//` quoting operator, which works like single-quotes: `print q/Yet another amount: $90.12/, "\n";` [download] There's a whole section in the perlop man page titled "Quote and Quote-like operators." That's something you'll want to read.	[reply] [d/l] [select]

`use Modern::Perl; my $dollars= 'I have $10.'; say $dollars; $dollars =~ s/\$/€/; say "Now $dollars";` [download] Output: `I have $10. Now I have €10.` [download] CountZero A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout.
