This chapter provides an overview of Intermec’s Interactive Reader Language (IRL). It
includes information on using the IRL Desktop on the JANUS 2050 and differences in
IRL that are exclusive to the JANUS 2050. Use this chapter in conjunction with the IRL
Programming Reference Manual
or the PC-IRL Reference Manual. These manuals
provide information on creating IRL programs.
What Is IRL?
Interactive Reader Language (IRL) is a high-level programming language used
to develop custom application programs for the JANUS 2050. Using IRL, you
can program the JANUS 2050 to display messages that prompt the operator for
information and provide feedback.
IRL programs are stored as text files on the JANUS 2050 drives or on the host
computer. They can be created in any DOS-based text editor and saved as an
ASCII text file. IRL features include:
•
backward compatibility with previous versions of IRL.
•
creation by integrated tools or PC-IRL.
•
advanced bar code input capabilities.
•
automatic and transparent power management.
•
efficient memory use.
•
simple and easy to use, for rapid application development.
IRL programs can be written directly on the JANUS 2050 or on a PC and then
downloaded to the JANUS 2050. Intermec recommends that you write the
programs on a PC and download them to the JANUS 2050. Intermec developed
PC-IRL to help write IRL programs on an IBM-compatible PC. PC-IRL also
downloads IRL programs to the JANUS 2050 using Polling Mode D protocol.
