Pulling out a value from the stack

Here are the instructions that let you pull out (pop) a value or a reference from the stack into another variable or field:

pop Pops a value out of the stack (doesn't store it in any variable)
starg Stores a value from the stack into a method's argument
stelem Stores a value from the stack into an element of an array (given the element ID and the reference to the array on top of the stack)
stfld (stsfld) Stores a value from the stack to a field ( and stsfld for static fields)
stind Stores a value from the stack at a specific memory address (which is pushed into the stack before the value is pushed)
stloc Stores a value from the stack into a local variable (it also has stloc.0 until stloc.3)
stobj Stores an object from the stack (that includes the reference to it) at a memory address, which is also pushed into the stack
The instructions that take IDs also have a shorter version with the .s suffix and some instructions such...
