Limitations of Virtual Machine Applications

The IDL Virtual Machine will run a compiled IDL SAVE file even if no IDL license is present. ITT Visual Information Solutions' aim with the IDL Virtual Machine is to facilitate IDL code collaboration and application distribution.

The IDL Virtual Machine displays a splash screen on startup.

SAVE files must be created using IDL version 6.0 or later.

No access to the IDL command line or IDL compiler is provided. Startup files are only executed when a command line is present. See Understanding When Startup Files are Not Executed for details.

The use of the IDL EXECUTE function is disabled. (In most cases, calls to the EXECUTE function can be replaced with calls to the CALL_FUNCTION and CALL_PROCEDURE routines.)

Callable IDL applications will not run in the IDL Virtual Machine.

The IDL Virtual Machine must be installed via the installation program provided by ITT Visual Information Solutions. You are prohibited from modifying the IDL Virtual Machine distribution.

Note
The IDL Virtual Machine installation program does not install the IDL DataMiner, IDLffDicomEX feature, IDL-Java bridge, or high resolution maps. If your application uses any of these features, users must install the full version of IDL (including the desired optional features) rather than the default IDL Virtual Machine installation. Although an IDL license will not be required to run in IDL Virtual Machine mode, certain features may require a special license.
