Stern and Ali Bahrami rewrote IDL for Unix on the Sun 3, taking advantage of the re-write to extend and improve the language.

Generated code classes are the result of compiling the user IDL code, which translates the high-level interface definition into an OS-and language-specific class base for use by the user application.

Typically, a CORBA implementation comes with a tool called an IDL compiler which converts the user's IDL code into some language-specific generated code.

It features multiple language bindings and IDL descriptions thus programmers can plug their custom functionality into the framework and connect it with other components.

Though RPC was later end-of-lifed with the operating system, HP contributed RPC to the Open Software Foundation, which incorporated its Interface Definition Language ( IDL ) into their DCE product, from which the same technology was later used for CORBA.

Software systems based on IDLs include Sun's ONC RPC, The Open Group's Distributed Computing Environment, IBM's System Object Model, the Object Management Group's CORBA ( which implements OMG IDL, an IDL based on DCE / RPC ), Mozilla's XPCOM, Facebook's Thrift and WSDL for Web services.

* OMG Tutorial on OMG IDL

Some ORBs, such as CORBA-compliant systems, use an Interface Description Language ( IDL ) to describe the data that is to be transmitted on remote calls.

The International Date Line ( IDL ) is an imaginary line on the surface of the Earth, that runs from the north to the south pole and demarcates one calendar day from the next.

The first program in the evolutionary chain to IDL that Stern developed was named Rufus ; it was a simple vector-oriented calculator that ran on the PDP-12.

In 1995, astronauts on board a space shuttle used IDL loaded on a laptop to study ultraviolet radiation.

Unlike MATLAB and IDL, PDL allows great flexibility in indexing and vectorization: for example, if a subroutine normally operates on a 2-D matrix array, passing it a 3-D data cube will generally cause the same operation to happen to each 2-D layer of the cube.

Like other interface description languages, IDL defined interfaces in a language-and machine-independent way, allowing the specification of interfaces between components written in different languages, and possibly executing on different machines using remote procedure calls.

This defined the mapping between the ODMG ODL and Smalltalk, which was based on the OMG Smalltalk binding for the OMG Interface Definition Language ( IDL ).

As a side effect of being able to be called from many programs, these systems also defined a standard way to call them, using an interface definition language, or IDL, to allow any language on the platform to understand the code inside the library.

CORBA uses an interface definition language ( IDL ) to specify the interfaces which objects present to the outer world.

These additional time zones prevent the earth from observing a single date for the instant when midnight crosses the IDL.

All IDL users are required to read and agree to the terms of the IDL EULA at the time that they install IDL.

Some time later the Spring IDL was adopted with minor changes as the CORBA IDL.

* OMG IDL: an IDL standardized by Object Management Group and implemented in CORBA for DCE / RPC services, also selected by the W3C for exposing the DOM of XML, HTML, and CSS documents

** IDL specification language, the original IDL created by Lamb, Wulf and Nestor at Queen's University, Canada

** OMG IDL, an IDL standardized by Object Management Group and implemented in the Common Object Request Broker Architecture and selected by the W3C for exposing the DOM of XML, HTML, CSS, and SVG documents

Crossing the IDL westbound results in 24 hours being added, advancing the calendar date by one day.

If the transfer had occurred at the preceding midnight, then Friday ( Julian ) would have been followed by Friday ( Gregorian ), a duplicate day with a 12-day difference appropriate both for changing from an Asian date to an American date ( equivalent to moving the IDL from the east to the west of Alaska ) and for changing from the Julian calendar to the Gregorian calendar during the 19th century.

The standard Java API contains numerous classes from the omg. org domain that are normally generated from the IDL files, released by the Object Management Group.

It can reverse engineer code written in C ++, IDL, Pascal / Delphi, Ada, Python, and Java, as well as import XMI files generated by external tools from PHP () or Perl code (, ) and export to various programming languages.

This example contains a divide by zero ; IDL will report an arithmetic overflow, and store a NaN value in the corresponding element of the < tt > y </ tt > array ( the first one ), but the other array elements will be finite.

In this release, the graphics supported by IDL were primarily Tektronix terminals and raster graphics displays.

The European Space Agency used IDL to process almost all of the pictures of Halley's Comet taken by the Giotto spacecraft.

IDL programmers can avoid many of these problems by using square brackets for array indexing, thereby avoiding conflicts with function names which use parentheses.

Files containing compiled routines use a binary tagged-data-structure format that has not been officially published but has been investigated and documented by users but also contain the following notice as ASCII text embedded within each saved file: " IDL Save / Restore files embody unpublished proprietary information about the IDL program.

Lipoproteins are classified by their density ( very low density lipoprotein ( VLDL ), intermediate density lipoprotein ( IDL ), low density lipoprotein ( LDL ) and high density lipoprotein ( HDL ).

HDF is supported by many commercial and non-commercial software platforms, including Java, MATLAB, IDL, Python, and R. The freely available HDF distribution consists of the library, command-line utilities, test suite source, Java interface, and the Java-based HDF Viewer ( HDFView ).

SOM and its IDL was developed by IBM in their Austin, Texas lab.

High-density lipoprotein ( HDL ) is one of the five major groups of lipoproteins, which, in order of sizes, largest to smallest, are chylomicrons, VLDL, IDL, LDL, and HDL, which enable lipids like cholesterol and triglycerides to be transported within the water-based bloodstream.

Most of these use an interface description language ( IDL ) to let various platforms call the RPC.

The IDL files can then be used to generate code to interface between the client and server.

CORBA then specifies a mapping from IDL to a specific implementation language like C ++ or Java.

At the OMG March 2012 meeting the OMG recommended the new IDL to C ++ 11 language mapping for adoption.

Some IDL mappings are more difficult to use than others.

This is also true of the IDL to Python mapping.

Since the C language is not object-oriented, the IDL to C mapping requires a C programmer to manually emulate object-oriented features.

A language mapping requires the developer to create IDL code that represents the interfaces to his objects.

: The initial specifications of CORBA defined only the IDL, not the on-the-wire format.

Low-density lipoprotein ( LDL ) is one of the five major groups of lipoproteins, which in order of size, largest to smallest, are chylomicrons, VLDL, IDL, LDL, and HDL, that enable transport of multiple different fat molecules, including cholesterol, within the water around cells and within the water-based bloodstream.

For certain classes of applications, the compiler system should also be able to handle IDL ( interface definition language ) files.

* Intermediate-density lipoproteins ( IDL ) are intermediate between VLDL and LDL.

An interface description language ( or alternatively, interface definition language ), or IDL for short, is a specification language used to describe a software component's interface.

* Thrift: IDL from Apache.

* John F. Kennedy International Airport, from when it was named " Idlewild Airport " (" IDL " IATA airport code )

FITS support is available in a variety of programming languages that are used for scientific work, including C, C ++, C #, Fortran, IGOR Pro, IDL, Java, LabVIEW, Mathematica, MatLab, Perl, PDL, Python, R, and Tcl.
