RE: RE: COBOL Question

[dennis@xxxxxxxxxxxx]

Hi again, Varma MVN:

I am compelled to also state the obvious:
when you have used the approach listed below, all of your subfile
moves can be done like:
MOVE FIELD-1 OF WORKREC TO DFIELD1OF SFLREC-1
(or, if the names are consistant between WORKREC and SFLREC-1
- GREAT design IMO)  ...
MOVE CORR WORKREC TO SFLREC-1

Also, if you are updating the files:
   MOVE CORR WORKREC TO LGLREC-1,
   WRITE LOGICAL-1-REC...
or
WRITE LOGICAL-1-REC FROM WORKREC...

Now I feel better.  :^)

Hi, Varma MVN:

My solution has always been to create a WORKING-STORAGE record
from one of the logicals, then to use either of the following
methods to simplify the code:

    01 WORKREC. COPY DD-ALL-FORMATS OF LOGICAL-1.

....

    READ LOGICAL-1 INTO WORKREC
       AT END do something
       NOT AT END do something else
    END READ.
or
    READ LOGICAL-1
        AT END do something
        NOT AT END
            MOVE CORR LOGICAL-1-REC TO WORKREC
            do other stuff
    END READ.

Note that this is standard "good" COBOL practice, and not unique
to COBOL/400.

HTH

Hi Gurus,
        Please excuse me for this question , but I'm a total stranger
to
COBOL/400. 
I have 4 logicals in my program & depending on some conditions
either of
them should be used to load my subfile. What I want to know is
if I can
select one of the files so that all the subsequent moves from
the file
fields to screen fields are effected as moves from the particular
logical file. I guess I want to define a generic name which will
take
the value of a particular logical based on the conditions.

Obviously I'm trying to avoid code like this -
        If condition1 then
                Move from logical1 fields to subfile fields
        else if condition2 then
                Move from logical2 fields to subfile fields
        else if condition3 then
                Move from logical3 fields to subfile fields 
        else if condition4 then
                Move from logical4 fields to subfile fields
        Endif 

 I'm looking for some solution like this -
        If condition1 then
                Select logical1 
        else if condition2 then
                Select logical2
        else if condition3 then
                Select logical3
        else if condition4 then
                Select logical4
      Endif 
        Move file fields to subfile fields      


Is it possible? If so how?
Thanks

Varma MVN
