... A "Large" GIF

This is one GIF image created from the display in the session manager of a Sharp APL interpreter on a PC. (See Other Methods - Large GIFs for a description of how to do this.) Note how the text of the function remains unchanged as you reduce the width of the browser window, for example, to half the width of the function lines.

The font is ISIAPL and was designed by Joey Tuttle.

... APL-ASCII Transliteration

This transliteration scheme was defined by Jim Weigang. The HTML source specifies the default browser mono-spaced font with a size of 13pt.

... J instead of APL

The first example is "native" J. The font is

dbrl =: 3 : 0
   b =. y. = ' '
   1 }. ((1,b) *: 1 |. 1,b)#' ',y.
)

The next example is the same function with the two-character functions replaced by suitable words, for example, *: is replaced by Nand.

dbrlw =: 3 : 0
   b =. y. = ' '
   1 Drop ((1,b) Nand 1 Rotate 1,b)#' ',y.
)
