IFUNC: string -> function
Function IFUNC returns the internal function object with name funcName. This constructor is almost never used by the SALIERI programmer; its main purpose is to provide a consistent representation of internal functions in order to make them applicable like user defined functions.
An error condition occurs, if there extsts no internal function with name funcName.
Result = IFUNC("write")
Result = IFUNC("IFUNC")
Error in command-line:
Unknown internal function: WRITE
(occured while executing function "IFUNC")
