Library /sys$common/syshlp/pca$help.hlb Frequently Asked Questions, LIB$FIND_IMAGE_SYMBOL  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Can PCA measure shareable images activated "on the fly" with
    LIB$FIND_IMAGE_SYMBOL?

    Yes, if you relink against the image you want to activate. PCA
    uses a structure built by the image activator to find all the
    shareable image information it needs. By relinking the image,
    the image activator will know about the image and LIB$FIND_IMAGE_
    SYMBOL will work.
