Chapter 4 - BRI Commands Executing a Command With a Parameter Macro You execute a command with a parameter macro by typing the command followed by a $ and the macro name. For example, you can execute the READ command using the parameters stored in MYREADPARAMS with this command: READ $MYREADPARAMS Listing All Macros Stored in Memory Macros are stored in the non-volatile memory of the reader. To display a list of all the macros currently stored in memory, use the SET command with no parameters: SET The BRI returns a list like this one: MYREADMACRO=READ TAGID WHERE INT(20,2)=2000 MYREADPARAMS=\"TAG ID:\",HEX(0,8), \"NAME:\",STRING(18,20) WHERE INT(18)=1 AND INT(22) != 100 AND STRING(30)=\"ADDRESS\" OK> Displaying the Contents of a Macro To display the contents of a macro, use the PRINT command as follows: PRINT $ where is the name of the macro. For example, use this command to view the contents of the MYREADMACRO macro: PRINT $MYREADMACRO The data is returned in a format that can be used in a subsequent BRI command.

Chapter 4 — BRI Commands
Basic Reader Interface Programmer Reference Manual
115
Executing a Command With a Parameter Macro
You execute a command with a parameter macro by typing the command followed
by a
$
and the macro name.
For example, you can execute the READ command using the parameters stored in
MYREADPARAMS with this command:
READ $MYREADPARAMS
Listing All Macros Stored in Memory
Macros are stored in the non-volatile memory of the reader. To display a list of all
the macros currently stored in memory, use the SET command with no parameters:
SET<CRLF>
The BRI returns a list like this one:
MYREADMACRO=READ TAGID WHERE INT(20,2)=2000<CRLF>
MYREADPARAMS=\“TAG ID:\”,HEX(0,8), \“NAME:\”,STRING(18,20) WHERE
INT(18)=1 AND INT(22) != 100 AND STRING(30)=\”ADDRESS\”<CRLF>
OK><CRLF>
Displaying the Contents of a Macro
To display the contents of a macro, use the PRINT command as follows:
PRINT $<NAME><CRLF>
where <NAME> is the name of the macro.
For example, use this command to view the contents of the MYREADMACRO
macro:
PRINT $MYREADMACRO
The data is returned in a format that can be used in a subsequent BRI command.
Deleting a Macro
To delete a macro from memory, use the SET command with no data after the
macro name as follows:
SET <NAME>=<CRLF>
where <NAME> is the name of the macro.
For example, to delete MYREADMACRO, use this command:
SET MYREADMACRO=<CRLF>
