NaBytecode

append bool append(Statement statement, string error)
bool append(Statement statement)
bool append(string statementStr, string error)
bool append(string statementStr): Adds a statement at end of existing bytecode
argSize uinteger argSize(uinteger argIndex)
clear void clear(): Discards any existing bytecode
load string[] load(Statement[] statements)
string[] load(string[] statementStrings): Loads bytecode. Discards any existing bytecode
resolveArgs bool resolveArgs(): Changes labels to label indexes, and resolves addresses, in arguments
verify bool verify(string error)
bool verify(): Verifies a loaded bytecode, to make sure only valid instructions exist, and correct number of arguments and types are loaded No more statements should be added after this has been called
