Generally speaking, C has a few models of how to do this.
One is called the "common" model - where what you say is true.
The other is called the "strict ref-def" model; where you can only
have one definitio

compilers account for this.

Where are your external references in program 1?

Yep, adding the ENTRY statement fixed it. Not sure how I missed its
necessity.
Thanks to Paul and Charles for chiming in.

I can't get some
I can't get some EXTRN variables to resolve at link-edit time.
Prog1 has:
VAR1DC A(Equate1)
VAR2DC A(Equate2)
Prog2 (separate CSECT, source file, etc.) wanting to reference those variables,
has:
EXTRN VAR1
EXTRN VAR2
...
VAR1E DC A(VAR1)
VAR2E DC
