When evaluated, this vm instruction bitwise left shifts the
source integer value by the count integer value.
The result is placed in the target word as an Integer data
type. Both words are assumed to be integer types (the types are not
checked). There are no conversions made between different types.
The result will be returned as an Integer type. This instruction will
never return an Error value. After the operation, the Instruction
Pointer is promoted. The operation of this vm instruction is expressed
in the following C expression:
Name

AIS Types count regoffset integer source regoffset integer target regoffset (word:integer)

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.
