Easy:
Welcome to J! (ctrl+d to quit) 4.05+GDS changes/Feb 16 2008/19:19:49
foo =: verb define
a=.0 [ b=.0 [ c=.1 NB. default values
".@> y. NB. actual parameters
(a + b) * c
)
foo 'a=.2';'b=.5'
7
Variations could use:
0!:100 >y.
".;._2 y NB. for passing 'a=.5; b=.10;'
Not that I'm really advocating this scheme. In J, you don't have
the safety net of a compiler which catches typos in parameter names
(as, say, Ada compilers would do).
