Script for nested reference attachments

Good Day,

I am attempting to write a script for making a nested reference files direct attachment and then detach the nested reference file.  My script looks like this;

REFERENCE MAKEDIRECT cn_compile.dgn->*

REFERENCE DETACH cn_compile.dgn

When its run, the files in the stated file do not become direct attachments, but does get detached.   I think its because MicroStation is waiting for an acceptance for the direct attachment.  How can I script to accept it?

Many thank in advance
