Re: RPG III to RPG IV

     Eric,
     
     Since you are planning on translating OPM RPGIII, there's a few 
     things to plan.
     
     1) Activation groups -- I'd suggest using the default activation 
     group parm on the CRTBNDRPG command. (That's DFTACTGRP(*YES)) This 
     will make your RPGIV programs run in the same activation group as 
     standard OPM programs. 
     
     2) Debugging views -- This compiler option can really affect object 
     size. Depending on your environment, you may be able to get by with 
     *STMT or *SOURCE. *LIST makes BIG objects, but will allow debugging 
     on production systems where source is not available. 
     
     3) Compile optimization -- Can improve performance and reduce 
     object size, but be careful.....
     
     
     In general, you probably won't see any change in response time. A 
     lot of your choices are going to depend on your production 
     environment and support needs. Start off with DFTACTGRP(*YES) and 
     the potential for runtime problems will be significantly reduced.

Since few monthes we plane to translate ours old RPG III programs to RPGIV,
but ....

    - What about performance, especially for interactive programs, do they
need more memorie ?
    - What about disk space (objets and sources) ?
    - Other problems ????

Do anybody have experience on it ?

Thanks,
