The CONST Method of VPGL Language make and emits a new VPGL Data Object such as number, string, array, dictionary, etc.
CONST takes 1 input and 1 output with option field mandatory. CONST starts on arriving a object from input 0. And create a object described literal in option field, then emit it to output 0. If option field is empty or malformed literal, VPGL executor reports error.
The the object reference as input 0 is discarded. (After that If this pointed object has no referer, it will be recycled.)
