hi kim,

yes, i’ve found that i can’t “infix” an assigned function,
but if you’re using an adverb (as in your example) you
can make it work like this:

q)g:{x+y}
q)3 g’ 4
7

hi Jack,

thanks for your quick reply.

i am the opinion that this can be done, since the built-in function xbar
is also an assigned function which can be used as an infix operator.

Cheers,

Kim
