Keep in mind that the ACUCOBOL-GT runtime will, by default, search for your "CBLCONFI" file in the "ETC" directory off of the root. However, in PC-based LANs, a subdirectory may be re-mapped as a root directory. For example, "C:\USR\BOB" may be remapped as "D:\". If the directory is remapped in this way, and the client is logged into D:\, the runtime will look for the configuration file in "D:\ETC", but will not find it. In this case, the runtime will proceed without the configuration file. You can avoid this possibility by explicitly designating the location of the configuration file with the local environment variable A_CONFIG.
