Sure but then *that* will not trim the trailing attributes.....
If you dim it to hold every element, and then write it back you just get the
exact same problem with which you started.
Extra empty attributes.
The solution you already had, to matread it, blank rec(0), then matwrite it
That works.

No spaces in the fields, nothing in them at all, just a line of attribute
arks with nothing in between.
Your trick below *does* work by the way, and it's essentially what I did.
I just set Rec(0) to nothing before the MATWRITE and that did it.
But I was also surprised that Andy's trick of just matreading and then
atwriting didn't work.
You have to set Rec(0) to nothing in between
I've just realised WHY that probably is ... Rec(0) is full of FMs ...
If you dimension your array to hold every element of the record
without* overflow, it'll work fine. I bet the MATWRITE tests if (0) is
mpty, and if it's got overflow in it ...

Tried that one.
What it actually does is store all the trailing attributes in the "header"
nd
hen append them back to the record when it writes it out.

hat flavour? That ALWAYS worked for me on PI.
Let's say your dict declares up to, say, field 20 and you know there
shouldn't* be anything beyond it.
Sounds actually, like you are in PI mode so ...
eclare your MAT as 20 long :-)
dd a line before the write which says
IF CONVERT( REC(0), @FM:" ", "") EQ "" THEN REC(0) = "" ELSE PRINT
Record ":ID:" contains extra data!"
So basically, you're dumping what you don't want into element 0. The
onvert checks that it really is nothing before zeroing it.
I'm guessing it's not working for you because somehow there are actually
paces in those fields you think are blank (ED gets rid of trailing
paces ...)
You can pull the same stunt for PICK mode, just remember the extra
ntries will end up in the last element of the array.

How about :-
OPEN 'FILENAME' TO FILEVAR ELSE
STOPM 'Cannot open FILENAME'
END
IM REC(500)
ELECT FILEVAR
LOOP
WHILE READNEXT ID
MATREADU REC FROM FILEVAR,ID THEN
MATWRITE REC TO FILEVAR,ID
END
REPEAT
ND
ATWRITE trims trailing blank attributes as it writes the data away
heers,

ubject: [U2] Trim trailing attributes off records
iven that you have a file with thousands of records, each with dozens of
railing attributes which are empty.
How can you pick up the file and drop it back down with all those empties
rimmed off?
