I think he means that it pops an operation into the hl register.  ops is a
stack of pointers ... each value points to a pending operation.  So, a
certain call could end on a number of different calls if it has this at the
end:

 call _load_ram_OPS
 jp (hl)

where the end jump is what you put on the stack.
