5WORDWRAP(STR,IEN,GL,LM) ;Wraps words at spaces normally and will breakup long
6 ; words at a delimiter & wrap at those break points
7 ; Input: STR - a text string
8 ; IEN - ien of global
9 ; GL - global root
10 ; LM - left margin
11 ; Output: Populated global (usually in ^TMP)
12 ;
13 ; When a long word is encountered, i.e. text with no spaces, an
14 ; attempt will be made to locate a delimiter & break the line there.
15 ; If it can't find a valid delimiter without a restricted scenario,
16 ; i.e. a number like 1,000 , then it will be forced to break at the
17 ; End of Line (EOL).
18 ;
19 ; Delimiters searched for and order they are picked for use:
20 ; preferred: , ;
21 ; alternate: : =
22 ; do not use: - . ) ( / (to critical, used in dosing)
23 ; example: "TAKE 1/2-1 TAB(7.5MG) TABLET(S)"
24 ;
25 ; Key Variables: WORD - current word from text string
26 ; WORD1 - 1st part of word that will fit
27 ; WORD2 - 2nd part of word for new line
28 ; WORD0 - remnant that won't fit on the new line
