Wow. Thanks Chris.
Now I get it ... when I was trying out the new format function I wasn't passing
it the complete parameters like so:
NB. convert to zero padded 2 digits
'r<00>' 8!:0 2
|rank error
| 'r<00>' 8!:0 2
So now I can just write my zero pad function as:
zeropad=: dyad define
('r<0>' append (format x) append '.0') (8!:2) y
)
5 zeropad 3
00003
5 zeropad each increment integers 10
┌─────┬─────┬─────┬─────┬─────┬─────┬─────┬─────┬─────┬─────┐
│00001│00002│00003│00004│00005│00006│00007│00008│00009│00010│
└─────┴─────┴─────┴─────┴─────┴─────┴─────┴─────┴─────┴─────┘
This is great! Thanks again. :)

'r<0>5.0' (8!:2) 123
