Library files used by code events

Files, variables, and records used by generated apps.

libdbapp

The libdbapp package is part of the BAM template set located at $GSTDIR/bin (or, if you are on a Mac, $GSTDIR/Contents/MacOS)/src/ag/tpl/dbappversion. The compiled binary versions are stored in the /bin directory. Source files are accessible at /src directory.

Each file has a specific role providing functions, declared public variables, and constants that are used in the generation of the code. When a generated program is built, these files are linked with the other program files to create the executable application.
