By default, this COBOL system already supports much of the RM/COBOL syntax and behavior. Additional RM/COBOL-specific syntax that has been added for compatibility is documented in the section RM/COBOL Syntax Support in your Language Reference.
You can also enable additional RM/COBOL behavior using certain Compiler directives. Using these directives when you submit your RM/COBOL source programs to this COBOL system ensures that most of the programs are accepted the first time they are submitted. There are still certain compatibility issues between the two COBOL systems, which are detailed, with any possible workarounds, in the RM/COBOL Conversion Issues section.
There is also a modernization tool available that helps to locate and transform incompatibilities in your legacy projects, and makes them compliant in this COBOL system. This tool is provided as an AddPack, available under the Visual COBOL Addpacks product entry (see version 2.2 release 0), in the Product Updates section of the SupportLine website (http://supportline.microfocus.com).
Users of this AddPack should also join the ACUCOBOL-GT Modernization community group. Through this group, you will have direct access to Micro Focus SupportLine, Technical Services, and Development staff members, as well as other users who are modernizing their code. To join the group, first join the Micro Focus Community (community.microfocus.com) if you have not already done so, then provide your Community account name to your sales representative, who will request access on your behalf. You will receive email notification when you have been added to the group.
