I know i remove my leading zeros with %char, and i know i can remove a 
decimal just by moving to a character field.  but with the use of %char or 
%editc or some combination can i remove leading zeros and suppress the 
decimal point.
ie Numbfield 7.2  (1234.21)
have it return (123421)

Tom,
     
This is the beauty of ILE.  You don't like the way a BIF does something, 
write your own!  Very simple to make a function that does exactly what 
you want the way you want it and stick it in your directory for binding. 
Give it whatever name you wish.  And then just call this function.
     
I understand that programmers are not wanting to do this, but it is the 
only real logical way to go.  If you're not doing it today, I can almost 
guarantee you that you will be someday.
     
It is really not that hard to build your own binding directory.  Put your 
headers (pr declarations) into a /copy member.  Now in your programs you 
have, what, one extra line of code at the beginning?
     
/COPY MyBind
     
And a few extra parameters to give when you compile.  Now you can use your 
own functions in your programs.  IBM does something  you don't like?  Change

it and give it a new name.
     
I think the good folks at IBM could of written this BIF either way, leaving 
in
leading zeros or taking them out.  Either way they did it, someone wouldn't 
of
liked it <g>
     
Incidentally, the VALUE did remain unchanged.  '   123' is equal to one 
hundred
twenty three.  Also consider that the number you are converting from could 
be
in many different formats, IBM's version of BCD (Packed), Zoned, Binary.  Of

those
only one actually has the zeros and that is Zoned.  I think the argument 
that
the original value had 0's is a mute point, because it's a number, not a 
character.
     
I think we are going to find more and more that IBM is doing things 
differently
then we would of wanted them done, and it is going to be much easier to just

build
our own functions to do them the way we want them to.  For every way IBM 
does
something, there's going to be 20 different ways people think it should of 
been
done.  You can please some of the people some of the time...
     
Regards,
