ACUCOBOL-GT provides many configuration variables and run-time library routines to tailor the environment and to help take advantage of host-specific capabilities. Configuration variables are documented in Appendix H. Configuration Variables. Library routines are documented in Appendix I. Library Routines. Windows-specific information is documented in A Guide to Interoperating with ACUCOBOL-GT as is information on working with transaction processing and message queueing systems on IBM and other hosts.
Following is a select list of configuration variables, runtime library functions, and host-specific capabilities pertinent to interface programming and configuration.
