I just want to know if in the ADAREP output, there has been any changes in the previous versions in regards with the File Definition Table Layout. Since what version the Layout is like the one below? * * * ## Type I Name I Length I Format I Options I Parent field(s) Fmt ## SUPER I H1 I 4 I B I NU I AU ( 1 - 2 ) U Thanks!!! ---

Hello Andreina, this FDT report should come from an Adabas Open Systems database. Generally it bears the same information as a Mainframe ADAREP. However, the layout is slightly different and Open Systems differs in some Adabas features (e.g. ability to assign a format to a superde, HF option, etc.) HTH, Marbod ---
