NB. I generate a list of integers: a=.000 012 034 678 020
a 0 12 34 678 20 NB. Of course, J removes leading zeros. 5 1$ a NB. I invert to a column of integers 0 12 34 678 20 NB. Now I want to fill the leading zeros back in in the column display, so I try the fill (fit) conjunction: 5 1$!.0 a 0 12 34 678 20 NB. Didn't work. What do I have to do to get a verb f, that leading zero fills in the columnar display: NB. Like this: f a 000 012 034 678 030 I need a general verb that can take any list of integers, and turn them into a column of leading-0-filled integers. Does the result of the verb f have to be a literal? Skip ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
