Formatting output

["Guillaume Dargaud" <dargaud(at)sung3.ifsi.rm.cnr.it>]

I want to format a string output but can't get it straight. Basically I want
floats to converts to a string with no space, no decimals and no dots.
I've tried many ways, here's the latest:

FOR i = 0, OrbNum-1 DO xtn[i]=STRING( $
 fix(OrbArray[i,0]),fix(OrbArray[i,5]),$
 fix(OrbArray[i,6]), FORMAT='(I," ",I,"h",I)')

But it comes out with spaces...
