Re: File Fields as array elements

I saw a similar answer as to what I'm going to give. Nevermind how the
fields appear in the file. All you need to do is list the fields in order
of a datastructure.

Assume Sales1 through 4 are defined as decimal 5,2 small yes but you'll
get the point.

* FSPECS
FFILENAME.... yadda yadda yadda.

* DSPECS
D salesDS DS
D Sales1
D Sales2
D Sales3
D Sales4
D Sales 1 20 2 Dim(4)


Since the fields are defined by the file... do not redefine them in the
datastructure... just simply list them. Then when you define the array...
you need to start at 1 and multiply the number of fields by the length.
4 * 5 = 20.... just specify the precision. 2 decimal points. Dim it 4
times to get your array.

In RPG, is there a way to refer to a field in a file by its relative
position in the file?

E.g. File with 10 fields use array element FIELD(5) to get to 5th
field.

I have a file with 53 weekly buckets for a number of different pieces of
information(sales, cost, rebates, etc) so there are > 300 fields.



I know I can define an array in the I specs and list the fields one at a
time but is there any other mechanism I can use that would allow me to
access the fields in the order they exist in the file(using array like
syntax). Maybe a Data structure or SQL?



Any thoughts would be appreciated



Thanks,

Mike
