Removing Blank Lines Problem
Posted: Friday, December 01, 2006 5:06 PM (EST)

I have a grid, text values, APL+WIN 6.4:

z„'TableMant.fGrd.gdMTI' Œwi xText' (¼TblRows) (¼3)

½z
10 3

(0¬½¨z[;1])šz
DOMAIN ERROR
(0¬½¨z[;1])šz
^ ^

0¬½¨z[;1]
1 1 1 1 1 0 0 0 0 0

      (
      (1 1 1 1 1 0 0 0 0 0)šz
A04.0 A04.0 ABCD
A04.1 A04.1 DEGH
A04.2 A04.2 DAFT
A04.3 A04.3 DAPD
A04.4 A04.4 RSFT

What changes do I have to make to the mask expression to make it work directly?

Thanks,

/mas

Just in case you didn't figure out why, the ½¨ returns a vector of vectors, the 0¬ doesn't change that, and the š can't take a nested argument. I generally use a †¨½¨ to avoid that, or ¹½¨ if you're sure all the items are vectors.

To err is human, but when the eraser wears out ahead of the pencil, you're overdoing it.
