Compiler Conversions Most MPE V/E applications will run in CM on MPE/iX without recompilation. Simply restoring the application onto an MPE /iX-based system enables you to immediately execute the application in CM. You may choose to continue development and maintenance of an MPE V/E application after its migration to an MPE/iX-based system. Many MPE V/E language compilers are available also on MPE/iX in CM to provide support for migrated MPE V/E applications. Because there is no COBOL 68 compiler available on an MPE/iX-based system, COBOL 68 applications must first be converted to COBOL II/V. Refer to the COBOL II/3000 Conversion Guide (32233-90005). Recompiling an application using NM compilers can provide increased performance and greater access to features offered by HP-PA, although modifications to the migrated source code may be necessary. To determine if there are any differences between the MPE V/E implementation of a language compiler and the MPE/iX implementation (either CM or NM), review the appropriate language migration guide (listed under "Documentation and Training" in Chapter 1, "Introduction and Migration Overview").
