J hides the details of pointers and memory allocation from the programmer, so it is rarely, if ever, neccesary to do this. However, for those times when there is no better substitute, J provides access to these low-level details:
var =: 52 NB. Any variable (including data, functions, operators etc)
var_addr =: 15!:6<'var' NB. Get address
new_var =: 15!:7 var_addr NB. Set address
