======Synopsis:======
[[call]]

======Description:======
[[CALL]] produces a gdb/dbx-like stack trace of the alias currently being
executed.  It returns a list of the commands currently being executed,
tracing back from the current command, to the command that called it,
and so forth until the [[CALL]] command itself it listed.  A deeply nested
alias might have the following alias stack:

      [ 0] call
      [ 1] go
      [ 2] get_set
      [ 3] get_ready
      [ 4] on_your_marks
      [ 5] /superalias

In this example, [[CALL]] was run from the "go" alias, which in turn was
called from "get_set", which was called from "get_ready", and so on, all
the way down to the original command executed.

Command names appear precisely as they are typed in (which means, if
an alias is called with a / in front of it, the slash will appear in
the stack listing).  Additionally, in the (unlikely) event that EPIC
were to crash, [[CALL]] is executed before the client terminates, to aid
in debugging.

======History======
[[CALL]] first appeared in EPIC3.001.
