Is it possible to link source files with Merlin Pro 2.43???

[netcoking@aol.com (Netco King)]

I use Merlin Pro 2.43 which I bought the original disks but no
accompanying diskettes.

Can anyone tell me how to "link" source files?  In other words, when a
source file is assembling, I would like for it to "link" in another source
file which is stored on the same diskette.

This way I can keep one hardware equate source file on disk and not have
to replicate the equate table in every other source file I create.

Hope this doesn't sound unclear.  Thanks for any help.
