Cows allows to easily output strings and variables. Everything you display within Cows scripts will be simply inserted in the resulting HTML file.

14.1 The Echo Function

Synopsis

echo(string);

Description

echo() prints string into Cows' output; string can be any valid expression:

echo ("literal string");
echo (variable);
echo (variable_1 + variable_2);

Example

The following script displays a quotation; please note that we must explicitly add newlines since echo() produces a verbatim copy of a string.

echo ("Man is the only animal that can remain on\n");
echo ("friendly terms with the victims he intends to\n");
echo ("eat until he eats them.\n");
echo ("-- Samuel Butler\n");

This is Cows' output:

Man is the only animal that can remain on
friendly terms with the victims he intends to
eat until he eats them.
-- Samuel Butler

Example (2)

Strings are passed as variables.

quote  = "You can't eat your friends and have them too.\n";
author = "-- Franz Kafka\n";
echo (quote);
echo (author);

This is Cows' output:

You can't eat your friends and have them too.
-- Franz Kafka
