CAUTION:
Save your macro source code.
You cannot recreate the source statements from a compiled macro.
(google translation: 你不能重新创建一个宏汇编源语句.
Therefore, you must save the original macro source statements if you want to change the macro. For all stored compiled macros, you should document your macro source code well. You can save the source code with the compiled code using the SOURCE option in the %MACRO statement or you can save the source in a separate file. If you save the source in a separate file, it is recommended that you save the source code in the same catalog as the compiled macro.
