When you use indirect calling, the name of the subroutine can contain odd
characters that wouldn't normally be allowed--though on some platforms you can
also quote the call, e.g.:
CALL "my-sub**"(parms)
Datatel (eg: Ellucian) does this in certain places allowing their
clients the ability to plug in custom subroutines for various things
like GPA calculations, repeat policies, etc.

I've not encountered this is my career previously, but now I'm seeing a system
written almost entirely with the use of indirect calls in Universe BASIC.
That is
SOURCE = "*SOME.PROGRAM"
...
CALL @SOURCE(INPUTS)
Is there some advantage to the use of indirect calls that a system would be
written entirely in this fashion?
