Re: Using an Expression to control a FOR loop

Just a bit of a warning, writing a delimited parser is a bit of a pain. If
you are on V5R4 or later I would suggest using the CPYFRMIMPF, but maybe
that doesn't work with QNTC?

Anyway, keep in mind that when you write a parser like this, you really have
to read the file character by character to really tell when a quote is a
quote and not a string delimiter.

Just my opinion, but it always seems easier than it really is.

of Excel versions that are/will be un-supported by Apache POI.

I guess I just thought a [comma, tab, pipe] delimited file parser (my
upfront screen asks what the delimiter is, and whether some/all fields
are surrounded by double quotes) would be more generally useful to me.

Arthur,

First it determines 'max' field attributes for every column in the .csv

file and then displays a subfile showing the 'DDS'.

Why convert to *.csv file format first if they are giving you a
spreadsheet? Scott has published articles on using HSSF to read the
spreadsheet directly from your RPG program using a service program.
Here is
one link:

The 2nd pass reads the data for the sole purpose of building a string

that exactly mimics the DDS record layout. That's why ...

Out of curiousity, how then are you handling negative numbers?
