COBOL-to-Java Conversion tool
▪ Fully Automated Migration of Mainframe COBOL (all versions) to Java
▪ Migrated code is pure Java 1.6 or greater
▪ Performance is maintained and even enhanced in some cases
▪ Each line of original code is copied to the Java code for references
▪ Migrated code
▪ Is scalable to any number of users
▪ Is structured and easily maintained under Eclipse® IDE
▪ Integrated easily with other Java applications
▪ Includes built-in CICS® preprocessor and emulator
▪ Built-in SQL preprocessor converts SQL calls to JDBC
▪ Online code (formerly using CICS) runs under an application server such as
Apache Tomcat, JBoss, WebLogic, WebSphere etc

Runtime library functions
Conversion approach - 1
PROGRAM-ID. PROG1.…
public class Prog1 extends LANG-XXXCode
LANG - XXX Java
One source program (LANG-XXX) becomes one Java class
One LANG-XXX variable becomes one Java instance variable (attribute)
01 FIELD01 PIC X(5). private X field01 =factory_.makeX("FIELD01",5);
LANG-XXXJava
19
Conversion approach - 2
Each Code SECTION or PARAGRAPH becomes one Java method
X1 SECTION.P1.…P2.…
public LANG-XXX Delegate x1()throws Exception{perform(X1P1,X1P2);}public LANG-XXX Delegate x1P1() throws Exception { … }
LANG-XXX Java
Program control through “Delegates” (Method pointers)
GO TO P1.
return P1;
LANG-XXX Java
20
Conversion approach - 3
▪ Each LANG-XXX statement becomes one or more Java statements
MOVE A TO B.IF A = 'XYZ'DISPLAY 'YES'.
b.assign(a);if(a.equalTo("XYZ")) {
display("yes");}
LANG-XXXJava

Phased Implementation
▪ Phased delivery reduces project risk and allows for early implementation
▪ Phases can be defined based on the specifics of the project. Examples:
▪ Small subsystem chosen as pilot
▪ Converting core application while implementing external interfaces in second phase.
▪ During assessment MOST will analyze the options of phased implementation
▪ Phased project may require co-existence.

The advantage of MOST’s migration
Low risk / high quality projects ▪ Phased implementations on-time within budget▪ MOST‘s resources are the master in MF and open systems
Post implementation▪ Customer is self sufficient to maintain the applications▪ Ready for new enhancements and cloud implementation
Retain existing valuable business functions▪ No need for intensive user training
29
Lower TCO vs. rewrite, package▪ Complete automation using home grown tools ▪ Short time to implement
