NF BC Working With IRL
Running an IRL Program
You can start an IRL program using any of the methods described next.
Note: You cannot execute IRL programs over an Interlnk connection.
• At the DOS prompt, type this command to start the IRL Desktop and
immediately start running an IRL program:
irl [filename]
7
where filename is the name of the IRL program to run.
• From the IRL Desktop, choose the Run command in the File menu. The
desktop lists the program files in the current directory. Use and to
select the program you want to run and press .
• When you download an IRL program from the host computer to the
reader, append the Run command (//) to the end of the program. The
program begins running when the download is complete.
• Using a communications application on the host computer, send the Run
command to the reader. The command runs {IRL-1}.IRL, the default
program.
• Scan this bar code label with the reader to run {IRL-1}.IRL, the default
program:
Run IRL Program
*//*
*//*
The IRL Desktop checks the syntax of the program before it runs the program.
If the program contains syntax errors, the reader emits three low pitched beeps
and the desktop displays the line number(s) of the errors along with a message
describing the error(s). Correct the program and run it again. During a syntax
check, OK and Cancel buttons are displayed along with any error messages.
Choose OK to continue the syntax check. Choose Cancel to terminate it.
If the IRL Desktop finds no syntax errors, it displays the amount of memory
the program and symbol table use, and the amount of memory remaining.
Then the program begins executing at the first program statement.
Pausing an IRL Program
You can press to turn the reader off and place it in Suspend mode while an
IRL program is running. When you press again to turn the reader back on,
the IRL program resumes running.
You can also exit an IRL program and resume running it later. For help, see
“Resuming IRL Programs” later in this chapter.
