Purpose

---

  Perform HELP equivalent at any point in IDL call stack

Calling Sequence

---

  DXHELP, X0, X1, ..., [ LEVEL=LEVEL ]

Description

---

  DXHELP performs the equivalent of HELP for the variables at any
  level in the IDL call stack.
  The call level to be examined is determined by the current
  debugging "focus." By default this is the deepest level in the
  call stack -- where the breakpoint occurred. However, this level
  can be changed by using the DXUP and DXDOWN procedures.
  If the ALL keyword is set, then all variables are examined.

Inputs

---

  Xi - variables to be examined, either quoted or unquoted.
        Non-string expressions are diagnosed, but of course refer to
        the deepest call level. If the ALL keyword is set then the
        Xi parameters are ignored.

Keywords

---

  LEVEL - the call level to be examined, if not the current
          debugging focus.
  ALL - if set, then all variables at the current focus level are
        examined.

Example

---

  dxhelp
  Print all variables at current debugging focus level
