It worked for me, back in the day!

The User guide has a small section dedication to this:
6.2.3 Creating Arrays with the COMMON Statement

So it's supposed to wrok one would think.

Please compile the writer, reader and declaration modules with /LIST/SHOW=MAP
Look for your (array) variables in the "Allocation information for COMMON <your common or map name>"
Look for similar 'sounding' variables outside the Psect.

Show us! I expect it to be a silly programming oversight.

If needed 
Show us the MAP (or COMMON)
Show us the assignments from and to.
Remind us how you build the shareable (LINK /OPT )  and do the install.
And just in case, as with any and every support question:
Operating System version, Architecture, Compiler version.

I'm happy try it, but that's best done with an example close to your usage.

Cheers,
Hein
