When evaluated, this vm instruction performs the unary operation, specified by the immediate operator argument, against the data in the vector processing stack. There are no conversions made between different types. The initial values in the three pointer registers, the three increment registers, and the counter register are NOT altered by this instruction. This instruction may return an Error value. After the operation, the Instruction Pointer is promoted. The valid operator arguments are any immediate integer value, indicating the operation to be performed, or any one of the following symbolic operators. For each operator, the operation of this vm instruction is expressed in the following C expression:



(vmvecUnary operator)

Virtual Machine Instructions

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.
