I checked the archives because I remembered one or more discussions on reading file vs format. Every authoritative post matched what I thought - with one format in the file, it shouldn't matter.

Since I'm using multiple logicals over the same physical in one program, I like reading by format because I can RENAME to something meaningful instead of using the file name. (Too bad the %EOF and %FOUND don't work on the format name...)

Anyway, when I compile my program, it has no problem with the SetLL below but gives "RNF5201: The specified Factor 2 operand is not allowed for READE or READPE operation." on the ReadE. I retyped the line from scratch to rule out any phantom hidden characters.

Value is defined LIKE the key to the file, DIM(48)
x is 3,0 and was previously set for the element in the array I wish to access (in a for loop).

Shouldn't this work?

I get the same error on another file accessing by a single field, so it's not the arrary that is causing this problem.

     FIVLCATI1  IF   E             DISK    RENAME(IVFCATI:ATIVAL)

      /Free
           SetLL Value(x) ATIVAL;
           DoW Not %EOF(IVLCATI1);
             ReadE Value(x) ATIVAL;
             If Not %EOF(IVLCATI1);
               // do stuff
             EndIf;
           EndDo;
         Eval *INLR = *ON;
         Return;
      /End-Free


Naturally, I thought, "I'll just use the file name instead." Well, I get the same error that the operand is not allowed.
