For the most part, the presence of a file which has been modified with the Sir2000 Field Migration Facility has no effect on Fast/Unload processing. The exceptions are as follows:
- The ADD, CHANGE, and DELETE statements may not be issued for a RELATED field.
- When doing an unload with UAI, the Fast/Unload output contains all of the Sir2000 Field Migration Facility definitions, which can be used to recreate them during the Fast/Reload LAI operation.
- The UNLOAD field statement, if it references a RELATED field, causes the other of the pair of RELATED fields to be unloaded. This ensures that if a partial record is unloaded, both occurrences of a RELATED pair of fields are always unloaded.
- If
UAI SORT field_RorHASH field_Rcauses field_R to be implicitly unloaded (see UAI SORT or HASH and field unload order), and field_R is a RELATED field, then any UNLOAD field statement causes the other field of the RELATED pair to also be implicitly unloaded, after field_R.
