FACT(s) (Environment):
Progress 9.x
SYMPTOM(s):
Trying to read _Field field from _File metaschema table
INPUT/OUTPUT operations are not allowed with RAW, ROWID, or MEMPTR or BLOB type variables. (1844)
CAUSE:
There is no field named _Field in the _File metaschema table, however, there is a field named _Field-Map and that is the name the 4GL grabbed when _Field was referenced in the DISPLAY statement (the 4GL attempts to resolve names in this manner). The field named _Field-Map is a RAW field and RAW fields cannot be displayed using the DISPLAY statement. This is what caused error 1844.
FIX:
Modify the application source code so that it refers to the proper field name(s) or tables.
