You can get into trouble using "string" and "delimited by spaces" if any of
your fields have spaces in the middle, like a company-name might.
A better approach (for those without Supertool) is to write a routine that
sets pointers to the 1st and last characters of the field, and then adds to
the first / left pointer until it finds a non-blank character, then subtracts
from the last / right pointer untill it finds a non-blank character or
collides with the first pointer. Along the way you should also check for
commas in each field and enclose the (non-blank) part of the field in quotes
if there are any commas. And start by moving all numeric fields to something
with zero-suppressing picture clauses. If you don't feel like hard-wiring the
max field lengths, you can get them with the Cobol 'length' function or HP's
old ".len." pseudo-intrinsic.
Below is a Cobol macro from one of my pgms that does most of the work. Its
parms are the data-field and a numeric field whose value is the data-field
length. The output record is called "incomplete-rec".
To use it, first, in your startup
MOVE 1 TO RPTR (the output pointer)
COMPUTE CUST-PO-LEN = FUNCTION LENGTH (CUST-PO-C40)
and repeat for other fields,
then
%APPENDFIELD(SORT-CUST-PO#,CUST-PO-LEN#).
%APPENDFIELD(ANY-OTHER-ITEM#,ANY-OTHER-ITEM-LEN#).
and repeat for other fields.

Subject: [HP3000-L] Create a CSV file
I've read the archives - and the only info I can find on CSV files is
converting
to fixed from a csv file.
I was wondering if there was a way to create a *real* csv file on the 3000.
I don't have many resources - I can create a csv file with COBOL or with
QUIZ. What they really are is a fixed length file with commas in between the
fields. Problem is, if you open the file up in excel - there are extra spaces,
and
it doesn't handle it correctly (you can see the data fine - but if you need to
load it into a database or do a lookup - it includes the trailing spaces). I'd
have to do a trim in excel and re-save the file to get rid of the spaces.
Is there a way to do this in COBOL or even just from the OS?
