• All code is reformatted and restructured into standard COBOL;
• The conversion is transparent to the user. No changes in input method are required;
• The JCL is manually addressed to handle the differences

Screen/Program Features

• The tool will create the assembler macros necessary to generate a BMS map set definition and a COBOL copybook which reflects the structure of the BMS buffer;
