J programming language

[DanWebb314]

I wish the J programming language had a form set up as nice as this one.  I am trying to learn how to write code in J.  Try googling for help.  Almost nothing but Java comes up.  This line of code

M[j] = y

Is hard enough to convert to J.  This line of code:

y = M[j]

may be impossible.

Sorry Dan but I can't help you there.

i know nothing of J   
but - my first thoughts are....

M[j] = y

you are describing a function

y = M[j]

you are trying to assign a set of values to a single variable
