Area format in FUSER v41

Hi all,

Some time ago we built an utility to create area parameter objects on the fly. Our development was based on stacking commands and using


Everything was working until we wanted to use de extended features of Natural’s v41 (length bigger that 4 digits). We looked at the format of another area parameter from FUSER file, but with no luck.

Does anybody know:

  • What is the format that the editor accepts for an area parameter with extended features
  • How can I change between the v31 format and the v41 format in the editor from natural code.



I strongly recommend to use user API USR4201N from library SYSEXT instead of dealing with the internal data area format. Internal formats may change and your program falls over, while user APIs continue to work.
