[jawsscripts] Re: Character Index in String?

Some of my documents have unwanted "255" characters. I use this script with 
JAWS 10 to remove them.
Script clean ()
;alt shift r
let gs1 = GetClipboardText () ; clipboard to input string
let gs3 = "" ; initialize output string
let glen = StringLength (gs1)
SayInteger (glen) ; how many characters at start

; tell me if cleaning is necessary
if StringContains (gs1, "\255") then say ("yes",1) endif

; stop when no more 255 characters
while StringContains (gs1, "\255")
let gpos = StringContains (gs1, "\255") ; gpos is the position of the next 
255
;SayInteger (gpos) during testing

; copy to output all characters up to but not including 255
let gs3 = gs3 + SubString (gs1, 1, gpos-1)

; delete from input all characters up to and including the 255
LET GS1 = stringChopLeft (gs1, gpos)
endwhile

CopyToClipboard (gs3) ; output string to clipboard
let glen = StringLength (gs3) ; how many remaining characters
SayInteger (glen)

EndScript
