What causes this issue?

To ensure that specific coding does not cause any import problems with
different releases, this coding has been turned into comments. (Unless
it has been designed in such a way that it is <zh>not</>
release-dependent.) During "Initial Load of Objects", the system
temporarily turns the coding into comments, and does a syntax check. If
this syntax check fails, the coding is kept as a comment.

System Response

&V1& &V2& cannot be used.

How to fix this error?

If you still want to use &V1& &V2& with specific routine &V3&(&V4&),
turn the corresponding comment lines back into coding and correct the
coding so that it is compatible with the current release.
