30BFTG(path,filename,globalRef,incSubscr,width)
31 ;"SCOPE: PUBLIC
32 ;"Purpose: To load a binary file from the host filesystem into a global, storing
33 ;" the composit bytes as raw binary data.
34 ;" You do not need to open the host file before making this call; it is opened
35 ;" and closed automatically
36 ;"Input: path -- (required) full path, up to but not including the filename
37 ;" filename -- (required) name of the file to open
38 ;" globalRef-- (required) Global reference to WRITE the host binary file to, in fully
39 ;" resolved (closed root) format. This function does NOT kill the global
40 ;" before writing to it.
41 ;" Note:
42 ;" At least one subscript must be numeric. This will be the incrementing
43 ;" subscript (i.e. the subscript that $$BIN2WP^TMGBINWP will increment
44 ;" to store each new global node). This subscript need not be the final
45 ;" subscript. For example, to load into a WORD PROCESSING field, the
46 ;" incrementing node is the second-to-last subscript; the final subscript
47 ;" is always zero.
48 ;" incSubscr-- (required) Identifies the incrementing subscript level. For example, if you
49 ;" pass ^TMP(115,1,1,0) as the global_ref parameter and pass 3 as the
50 ;" inc_subscr parameter, $$BIN2GBL will increment the third subscript, such
51 ;" as ^TMP(115,1,x), but will WRITE notes at the full global reference, such
52 ;" as ^TMP(115,1,x,0).
53 ;" width -- OPTIONAL -- the number of bytes to store per line. Default=512
54 ;"*** NOTICE: width is not working properly. For now, just don't supply a number.
55
56 ;"Result: 1=success, 0=failure
57 ;"
58 ;"Example:
59 ;" write $$BFTG(path,file,"^TMP(115,1,1,0)",3)

111 ;"SCOPE: PUBLIC
112 ;"Purpose: This function will WRITE the values of nodes of a global (at the subscript

115 ;" Each line of the global is written out, in a serial fashion based on the ordering
116 ;" of the subscripts, with no line terminators written between lines.
