When evaluated, this vm instruction invokes the source
function, passing the number of arguments specified by the argcount
argument. The source word must be one of the function types
(either a built-in C function or an AIS Lambda object). The argcount
argument must be an immediate Integer, causing the top argcount
stack words to be passed as arguments to the function source.
The result word is placed at the target location. The operation
of this vm instruction is expressed in the following C expression:
Name
Format
AIS Types arcount immediate integer source regoffset word target regoffset word

AIS Lambdas are designed to be write-once-run-anywhere executable objects. This is accomplished via the virtual machine concept of software Lambda execution. Lambda virtual machines are designed to be mapped onto the actual host microchip at the server location, providing faithful Lambda execution wherever the Lambda may travel on the Internet. There are currently several virtual machines operating within Analytic Information Server. The DRM virtual machine uses a Dynamically typed Register Machine model to provide portable Lambda execution from high level dynamically typed instructions all the way to super fast microchip-level register execution. The DRM virtual machine runs in emulation mode during the testing and debug phases of Lambda development, and there is an AIS Lambda debugger available for Lambdas running on this virtual machine. During the final release phases of Lambda development, DRM virtual machine Lambdas are automatically converted to the NATIVE virtual machine on the host computer, using the just-in-time compiler. The NATIVE virtual machine is a faithful machine language translation of the execution rules in the DRM virtual machine onto the actual host microchip at the server location. NATIVE virtual machine execution runs at microchip-level execution speeds.
