11 Function: returns a pointer to the most recent condition frame,
12 or the most recent one before a specified frame.

15 Syntax:
16 dcl find_condition_frame_ entry (ptr) returns (ptr);
17 stack_ptr = find_condition_frame_ (start_ptr);
18 
19 
20 Arguments:
21 start_ptr
22    is a pointer to a stack frame.  The most recent condition frame
23    before this stack frame is returned.  The start_ptr argument can be
24    obtained by another call to find_condition_frame_.  If start_ptr is
25    null, the most recent condition frame is returned.  (Input)
26 stack_ptr
27    is a pointer to the desired condition frame.  (Output)
28 
29 Notes:
30 The condition history can be traced by repeated calls to
31 find_condition_frame_, starting with a null start_ptr argument and
32 repeatedly passing the output stack_ptr as input.
