Source Program Migration This section describes how to convert source programs written in Transact/V to native mode Transact/iX source. Since there are few, if any, changes to be made when converting from a Transact/V source program to a native mode Transact/iX source program, no automatic conversion utility is provided. Any changes required must be made to the Transact/V source program to convert it to a native mode Transact/iX program. If the program accesses data from files or databases created on a MPE V based system and the data includes real numbers, the native mode Transact/iX program should be compiled using the HP3000_16 option until data conversion programs are written to convert the data to the MPE/iX standard format for real numbers. Conversion If your programs do not use the PROC verb, there should be few if any changes to make. See the Migration Checklist later in this appendix for more related information. When migrating a Transact/V program on an MPE V based system to a native mode Transact/iX program on an MPE/iX based system, you should check to see if any of the missing and changed features listed in the previous sections affect the program. If there are any missing or changed features in the program you are migrating, refer to the appropriate section in this manual for information on altering your program so that it can run successfully with native mode Transact/iX. If the program uses any of the missing compiler options--the SWAP option on the CALL verb, or the UNLOAD and NOLOAD options on the PROC verb--you can ignore the compiler informational messages because program execution is not affected. For the commands used to compile and run Transact programs under MPE/iX, see Chapter 9.
