In ACUCOBOL-GT, as in HP COBOL, a program may directly or indirectly call itself. Such a CALL statement is termed a recursive call. By default, ACUCOBOL-GT creates a new copy of data for each instance of the program. To share the initial data with all recursive calls, as is the default with HP COBOL, set the RECURSION_DATA_GLOBAL configuration variable. For more information, see RECURSION and RECURSION_DATA_GLOBAL .
