Questions tagged [heredoc]

Although syntax can differ between programming languages, most heredocs start by putting a keyword, and end when the keyword is encountered as the only element on a line (no spaces, tabs or other characters are allowed). Perl example:

my $text = <<KEYWORD; #Any non-reserved word would do
This is some text.
It can contain $othervariables which will be replaced
Unless KEYWORD was between single quotes, in Perl.
