Syntax error
This error occurs when the JANUS 2050 does 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 JANUS 2050 is executing a program.
The program ignores nonfatal errors. If it is a fatal error, the JANUS 2050 exits
the program and returns to the IRL Desktop or DOS prompt.
The following table lists the error beep sequences and their meanings.
Sequence Meaning
LLL Syntax or compile error
LHL Nonfatal runtime error
HHH Fatal runtime error
L=low beep H=high beep
Resuming IRL Programs
You can exit an IRL program, perform other functions with your JANUS 2050,
and then resume the IRL program exactly where you left off. Other functions
you can perform before resuming the program include executing DOS
commands, running other IRL programs, and putting the JANUS 2050 in
suspend mode.
Exiting a Program So You Can Resume It Later
You will be able to resume an IRL program later if you exit it using one of these
methods:
•
The Exit IRL command
•
An application break sequence
•
The ED command (The E command has a D modifier, which instructs IRL
to exit to DOS.)
You can exit multiple programs that can all be resumed later. IRL creates a
separate FILENAME.RSM file in the current data path directory for each
program (where FILENAME is the corresponding program name). The .RSM
file contains parameters that allow IRL to resume the program exactly where
you left off. The .RSM file is deleted when you run or resume the program.
IRL also saves the name of the last program that was exited as described
previously into the {LATEST}.RSM file. Every time IRL saves the filename to
this file, it overwrites the last filename; therefore, the file always identifies the
last IRL program that can be resumed. This file is deleted when you run or
resume the program.
