Description

The ECHO command evaluates the expression and displays the results on the same line, no carriage return/line feed sequence is output unless the <exp> is a character expression and contains the 'C' style escapes as shown below. If more than one expression is specified and SET SPACE is ON, a single space is output between each expression. If SET SPACE is OFF, the expressions are output with no space in between.

Escape	Description
\t	Tab
\n	New line
\r	Carriage return

Clause	Description
AT <expN>	You may optionally specify the column at which the expression will be output with the AT <expN> clause.
PICTURE <expC1>	The PICTURE clause supports all picture template symbols listed in the @...SAY command.
FUNCTION <expC2>	The FUNCTION qualifier allows picture functions to be specified. Normally this can be done with the PICTURE qualifier by preceding the picture with '@'. If the FUNCTION qualifier is used the '@' is not needed.
STYLE <expC3>	The STYLE qualifier has been added for compatibility with other Xbase languages.

In Recital Mirage, the following style qualifiers are supported in <expC3>:

<expC3>	Style
B	Bold
I	Italic
U	Underline

Example

echo "price" at 10 picture "@!",1234.56 picture "$9,999.99"
echo "---------------\n" at 10
          PRICE $1,234.56
          ---------------
