The following section details changes that can affect programs originally written for the Version 2.3 ACUCOBOL-85 compiler.
Compiler Changes
New directory structure
Beginning with Version 3.0, a new directory structure is created when you load your Acucorp media. See the "READ_ME" file for the location of all Acucorp files. Note that the new directory structure may not be compatible with scripts you have in use at your site.
Runtime Changes
Relinking the runtime
If you relink the runtime, be aware that the Makefile in the "lib" subdirectory leaves the rebuilt runtime in the "lib" subdirectory. This change allows you to rebuild the runtime system and test it without overwriting the original runtime, and without renaming it. However, be sure to move the rebuilt runtime to the "bin" subdirectory, or move it to a directory in your path.
Alternate file systems
Check the "RELEASE" notes to verify the compatibility of older versions of Acucorp interfaces to alternate file systems such as Btrieve and INFORMIX.
