Re: Need to create a view over a physical file - but I don't want to - but I have to

Thanks for your reply Charles
So far, the article IS proving to be WAY beneficial.
I am going with the 2 separate set of fields
One set for the CPNAMT and one set for the PCTAMT
As you suggested, if one set has values, the other set has zeroes.
I have also found out that It is also possible that BOTH sets have zeroes.
AND I have just started, who the @#$$ knows what I will find as I delve
deeper into this

Alan,

That article should do the trick.

The only other thing I can offer is regarding CPNAMT and PCTAMT,
you've got two choices.

Include a single field in your view, or include both fields via a CASE
statement. I'd recommend the later. In which case one of the two
would be zero and the other presumably would be non-zero.

HTH,
Charles

that looks promising

Sorry about the subject description - but I couldn't think of what to put
in there that would convey the predicament that I face

I need to create a view over a physical that contains the following

fields

(believe me - NOT my design)

Name                             Type                            Length
FIELD01                  A                               63
FIELD02                  A                               63
FIELD03                  A                               63
FIELD04                  A                               63
FIELD05                  A                               63

Now - within the programs, each of these fields are moved to a separate
datastructure that is defined like this

D FIELDNBR             DS                  OCCURS(5)
D  CFREE                                 1     63
D  LLMT                                  1      3P 2
D  LLMTX                                 1      3
D  WFR                                   4     63
D                                                                DIM(5)
D  QTY1                                  4      5P 0
D  ITM#1                                 6     15
D  CPNAMT                                16     20  2
D  PCTAMT                                16     17  0
D  QTY2                                  16     17P 0
D  ITM#2                                 18     27
D  QTY3                                  28     29P 0
D  ITM#3                                 30     39
D  QTY4                                  40     41P 0
D  ITM#4                                 42     51
D  QTY5                                  52     53P 0
D  ITM#5                                 54     63
D  TYPE                          63     63

If TYPE is a 'C' then CPNAMT is the field to use
If TYPE is a 'P' then PCTAMT is the field to use

I also need to figure out how, when and  where QTY2 is used
I also need to analyze if there is anything else

At the moment all I am doing is staring at my screen, thinking whether or
not to re-design this whole file to be more meaningful, BUT what is
required is a view
As always any and all responses GRATEFULLY accepted

Thanks in advance
