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.
