Macros let you create shorter, more convenient commands. You can send two types of macros: • A command macro contains a BRI command or sequence of BRI commands to be executed. • A parameter macro contains a list of parameters to be used when executing a BRI command. Your macro can contain any BRI commands, command line parameters, and reserved keywords. Macros are stored in the non-volatile memory of the reader. The following sections explain how to create, invoke, list, view, and delete macros. If you prefer looking at command descriptions: • see "SET" on page 62. The SET command lets you create, list, and delete macros. • see "PRINT" on page 52. The PRINT command lets you view the contents of a macro. Basic Reader Interface Programmer Reference Manual 113

OK><CRLF>
Command:
READ “PRICE ”, INT(28,2), “QUANTITY ”, INT(30,2)<CRLF>
This READ command reads two numeric fields from a tag and finds three tags in
the field. This command also shows how to make the response more readable using
[LITERAL] parameters PRICE and QUANTITY. One tag also returns a read error for
the second field.

Creating and Using BRI Macros
Macros provide a shorthand method for defining and sending complex BRI
commands without sending all of the command line parameters each time the
command is used. Macros let you create shorter, more convenient commands.
You can send two types of macros:
•
A command macro contains a BRI command or sequence of BRI commands to
be executed.
•
A parameter macro contains a list of parameters to be used when executing a BRI
command.
Your macro can contain any BRI commands, command line parameters, and
reserved keywords.
Macros are stored in the non-volatile memory of the reader.
The following sections explain how to create, invoke, list, view, and delete macros. If
you prefer looking at command descriptions:
•
see
“SET” on page 62
. The SET command lets you create, list, and delete
macros.
•
see
“PRINT” on page 52
. The PRINT command lets you view the contents of a
macro.
