15.5.450 pop

pop [, num=num] , var [, var2 …]

Pops variables from the variables stack #stack (in last in – first out order). If num is specified, then it is taken to contain the number of symbols to pop from the stack; these are restored to their original locations. Next, any remaining arguments var, var2, etcetera are treated. Any named variables receive successive values popped from the stack, and any unnamed variables are taken to contain numbers of symbols to pop and restore to their original locations.
