+ | * There's a problem with trying to agree upon the I/O of existing functions in existing codes, because this would restrict coding. This problem arises when directly accessing existing methods within existing codes, such as: | ||
+ | * ''FUNCTION <name> type=<type> args=<# of args> | libName=<name of compiled library> | funcName=<name of function in library> | END_FUNCTION'' | ||
+ | * Agreement about the I/O of these directly accessed functions could severely tie the hands of the author(s) of the original code, and it is not feasible. | ||
