program Circular;

{ Simple program that demonstrates circular unit references via
|
|
a USES clause in the implementation section.
|
|
|
|
Note that it is NOT possible for the two units to "USE" each
|
|
other in their interface sections. It is possible for AA's
|
|
interface to use BB, and BB's implementation to use AA, but
|
|
this is tricky and depends on compilation order. We don't
|
|
document or recommend it.
