Appendix B Compatibility Issues This appendix provides guidelines on developing applications that will be portable at either source code or intermediate code level between Micro Focus COBOL for DOS and OS/2 and Micro Focus COBOL for UNIX. This portability is available using the INTLEVEL"integer" compiler directive. A description of this directive is contained in Appendix G , Directives for Compiler/Generator. The guidelines in this appendix describe programming methods that will allow you to make best use of this directive in creating portable applications. Additionally, this appendix documents certain features of the Micro Focus COBOL system which are supported in this release for compatibility purposes with previous releases of the system. These features are: * calling non-COBOL subprograms * non-COBOL programs calling COBOL subprograms * COBOL capabilities file: cobcap * commands to invoke the Micro Focus COBOL system components * optimizing intermediate code The features are provided only for backward portability; you are not recommended to use any of the above features in new applications.
