A Procedure’s Local Variables
Following the generation of the local variables, this area consists of:
L[1] = i
L[2] = j (initialized with a value of 5)
L[3] = an address pointer to the array "k"
L[4:35] = the array "k"
Once allocated, data in the local area is addressed relative to the current L register
setting using the L-plus-relative addressing mode. As illustrated, this mode can access
local data directly or can use the direct address as an address pointer (indexing is also
permitted).
