- lvarpop var [index [string]]
- The lvarpop command pops (deletes) the element indexed
- by index from the list contained in the variable var.
- If index is omitted, then 0 is assumed. If string, is
- specified, then the deleted element is replaced by
- string. The replaced or deleted element is returned.
- Thus ``lvarpop argv 0'' returns the first element of
- argv, setting argv to contain the remainder of the
- string.
