Abstract: A device is configured to execute a first program block associated with program code, and set a first value of a scoped setting associated with the first program block, the first value of the scoped setting controlling a manner in which a first algorithm is performed during execution of the first program block. The device is configured to detect a change in scope of the program code, the change in scope including execution of a second program block that is different from the first program block, and determine a relationship between the first program block and the second program block. The device is configured to set a second value of the scoped setting based on the relationship, the second value of the scoped setting controlling a manner in which a second algorithm, identified in the second program block, is performed during execution of the second program block.

Abstract: Disclosed herein are methods and compilers for compiling code. The methods and compilers disclosed can compile a callable compilable unit of code free of declarations and assertions that identify attributes of arguments expressed therein. The attributes of the arguments in the callable compilable unit of code are inferred by the compilers and methods disclosed herein from information provided by a call site that calls a compiler to compile the callable compilable unit of code.

Abstract: A method for retaining state information of a digital filter object in a dynamically typed text-based programming environment is disclosed. The digital filter object retains state information which includes the minimal amount of information that is necessary to determine the output of the digital filter object. The digital filter object generates the output of the object in response to the input of the object depending on the state information of the object. The state of the filter is stored in a memory and provided to the object as an initial value of the state of the object.
