7 ;
8 ; IEN IEN of the report element
9 ;
10 ; .STACK Reference to a local variable where the path will
11 ; be stored to.
12 ;
13 ; STACK Number of elements in the path (n)
14 ; STACK(i) Identifiers of the elements (i=1 - the source
15 ; element; i=n - the root element)
16 ; ^1: IEN of the report element
17 ; ^2: Where exactly the rendering process
18 ; has stopped (see $$XMLSTR for details)

28 ;
29 ;***** RENDERS THE REPORT INTO XML
30 ;
31 ; ROR8DST Closed root of the destination buffer
32 ;
33 ; TASK Task number
34 ;
35 ; [.SORT] Sort modes for the report
36 ;
37 ; [.FROM] Where to start/continue the rendering process
38 ; ^1: IEN of the report element
39 ; ^2: Where exactly the rendering process has stopped
40 ; (see the $$XMLSTR function for details)
41 ; ^3: IEN of the text line (if the 2nd piece = 3)
42 ;
43 ; You must not make any assumptions about structure of
44 ; this parameter (it can be changed at any time without
45 ; warning). The only exception is the IEN of the report
46 ; element. You can assign a positive value to this
47 ; parameter before the call to start the rendering from
48 ; the corresponding element.
49 ;
50 ; [MAXSIZE] Either the maximum number of lines to retrieve or
51 ; the maximum size of the output in bytes (append the
52 ; "B" to the number). By default (if $G(MAXSIZE)'>0,)
53 ; the whole report (starting from the point indicated
54 ; by the FROM parameter if it is defined) is retrieved.
55 ;
56 ; Examples:
57 ; 500 Retrieve no more than 500 lines
58 ; 4096B Retrieve no more than 4Kb
59 ;
60 ; NOTE: If the "B" suffix is used, the size of the retrieved
61 ; portion of the document can be somewhat bigger than
62 ; MAXSIZE! The last line of the chunk is not truncated
63 ; even if the size will be bigger than MAXSIZE.
64 ;
65 ; Return Values:
66 ; <0 Error code
67 ; 0 Ok
68 ; >0 Number of rendered lines
69 ;
70 ; If the maximum size (MAXSIZE) is reached, the identifiers
71 ; of the last item (it has not been added to the output buffer) are
72 ; returned via the FROM parameter. The next call of the function will
73 ; continue the rendering process starting from that item.
