Using the EXTFH Interface

Two basic requirements are needed to configure the ACUCOBOL-GT runtime to utilize the EXTFH interface:

  1. Specify the file system(s) that is using the EXTFH interface to access files.
  2. Dynamically load the EXTFH libraries using runtime configuration variables or by statically linking the EXTFH-compatible libraries with the runtime.

After you configure the runtime, the COBOL data access methods are unchanged. The same COBOL file I/O statements are used whether accessing native file systems or using EXTFH.
