DESCRIPTION:

     The contents of a joint/member/load group are incorrectly altered
when joints/members/loads contained in the group are deleted (DELETIONS
mode) and new joints/members/loads are created.  The following example,
including output, illustrates this problem:


STRUDL

     The workaround to this problem is to delete the group and redefine
it in the same manner as it was originally defined, but with the ACTIVE
modifier added to the DEFINE GROUP command as shown below:


STRUDL

     RELEASE DATE        VERSION        COMPLETION NO.
     AUGUST 1993         9301VAX             3062
