DGROUP Specifier Is Necessary to Access Local Data

2.20 MS-DOS

Summary: A COBOL program CALLs the Assembly routine that requires the specifier DGROUP: to precede the variable name to successfully access local data. For example, the following command does not access the local data as desired: mov dx, OFFSET show_n However, the following command works correctly: mov dx, OFFSET dgroup:show_n To work around this problem, include the DGROUP specifier. This problem does not exist in COBOL 3.0.
