ING_ABFDIR defines the directory name for the top-level directory to contain Applications-By-Forms object libraries and work files. Under this directory, a subdirectory is created for each database that contains ABF applications and, within that subdirectory, another subdirectory is created for each ABF application. The ING_ABFDIR directory level must have read, write, and execute permissions for group, owner, and world. If, however, the application designer redefines ING_ABFDIR to point to a directory of his own, he can optionally restrict permissions on the directory to read, write, execute to owner. It can be redefined installation-wide or locally.
