甭查了，你想调用都调不了，人家编译器内建支持
像_LStrCat3，如果我没记错的话，应该是
var s, s1, s2: string;
s := s1 + s2;
会调用它
_LStrAsg没印象，system.pas里写的是
This function is used when assigning to global variables.
Literals are copied to prevent a situation where a dynamically
allocated DLL or package assigns a literal to a variable and then
is unloaded -- thereby causing the string memory (in the code
segment of the DLL) to be removed -- and therefore leaving the
global variable pointing to invalid memory.
