Ok.  What has that got to do with questions about dbLoadTemplates?

The two are not related, other than the fact that both make use of macLib from 
libCom internally.  That's probably about the only code they have in common.

Don't you keep the history of your application sources in CVS or some other 
version control system?  This shows you one good reason to do so...

Why?  dbl is an st.cmd file command; it has nothing to do with the syntax that 
dbLoadTemplate() accepts.  It is looking for the keyword "file" followed by 
the name of a template file.  Section 6.20 of the AppDevGuide describes the 
formats it understands.

If you were meaning to expand your substitution files at build time you would 
use msi for that and give it a substitution file, using the same syntax that 
dbLoadTemplate() is looking for, and then you probably wouldn't use 
dbLoadTemplate() at all on the IOC.
