Reading directly into a DS

Hi folks,

I'm going in circles here and was hoping someone wouldn't mind helping me.
I'm trying to read data directly into a DS and then write the data to another file, either with an update or a write, using the data structure.
I know there are different styles, like READ file-name ds-name, and I'm not sure which is the preferred style.

First of all, we're on V5R4.
This program reads the records from an intermediate file and either updates or adds them to the master file.
The intermediate file was created using CRTDUPOBJ of the master file, which is why the record format is renamed.
The files each have 7 fields, of course with the same name.

1. I tried having a meaningful prefix on the F-spec but I received a compile error RNF2356, I think because there is a limit of 13 to the field name length.
What can I do to improve this?

2. I'm getting compile time errors:
*RNF7030 30 7 The name or indicator is not defined. (I.field1, I.field2, etc. for the 7 fields in the file)
*RNF7701 20 2 The data structure is not allowed for the operation. (Update ACCDOCR I and Write ACCDOCR I)

Any tips would be most appreciated.

Yours truly,

Here is my code (sans header comments):

// eFile Document Code file by Document Code.
FACCDOCCODLUF A E K DISK
