XHCS support by openFT

With XHCS, various codes can be used in a BS2000 system at the same time. openFT can utilize XHCS information to recognize the code being used. Depending on the type and scope of the information, openFT employs the XHCS conversion tables (either before or after a file is transferred as a text file) to convert a file to a code that can be processed in the target system.
