When an IRL error occurs, the reader beeps and displays an error message.
Press to clear the message and continue. The types of error messages are:
Receive error This error occurs when the reader is receiving a message or
protocol characters from the host.
Transmit error This error occurs when the reader is transmitting a message or
protocol characters to the host.
Syntax error This error occurs when the reader is performing a syntax check
on a program before running the program. If a program statement is invalid,
the error message lists the program statement and the problem. Edit the
program for syntax errors and run it again.
Runtime error This error occurs when the reader is executing a program. The
program ignores nonfatal errors. If it is a fatal error, the reader exits the
program and returns to the IRL Desktop or DOS prompt.
This table lists the error beep sequences and their meanings:
Sequence Meaning
Three low beeps Syntax or compile error
Low beep, high beep, low beep Nonfatal runtime error
Three high beeps Fatal runtime error
Note: The JANUS reader does not beep to indicate transmit or receive errors.
The next table lists problems that may occur when you run IRL programs on
the reader.
Problem Solution
The reader displays “Executing...” on
power up or prompts you for data on
power up.
There is not enough memory to run your
IRL program.
An IRL Program is running. Type or scan this Exit IRL Program
command:
Exit IRL Program
*/$*
*/$*
You need to free more conventional memory or run the
program without running the IRL Desktop. For help, see
“Freeing Enough Memory to Run an IRL Program” in
Chapter 7.
