Specifying Data and Program Paths
The directory that is current when the IRL Desktop is run becomes the path for
the data and program files. An exception is if the current drive is C or D. In this
case, the first drive the JANUS 2050 can write to becomes the path. You can
change the directory or view the current paths using the menus in the IRL
Desktop.
You can specify a default directory path for your IRL program and data files in
your AUTOEXEC.BAT file. This feature lets you control where files are stored.
To specify the default path, include the following lines in your
AUTOEXEC.BAT file.
To set the path for IRL programs
•
Enter the following command:
set IM_IRLPROG=[
drive][directory]
To set the path for IRL data files
•
Enter the following command:
set IM_IRLDATA=[
drive][directory]
If you set IM_IRLDATA path to a drive that cannot be written to, the JANUS
2050 defaults to drive G if a PC card is present; otherwise, it writes to drive E.
Data paths can also be specified in the IRL program by declaring the path in
the open statement for files A through Z. File 0 is the only file that cannot have
its path specified in an IRL program.
Using the Desktop
You can use the IRL Desktop to transfer and execute IRL programs. To open
the IRL Desktop from the DOS prompt, type:
irl
Then press
e
.
Or scan the bar code:
*IRL*
*IRL*
If you want to load a protocol handler for a designated port and execute the
IRL Desktop, you can include an argument in the command line. To load a
protocol handler, enter the following command at the JANUS 2050 DOS
prompt:
irl -[{
port}{ph}]
