Hi Gordon

Thanks so much again for your help. I've just got home and had to try it out 
straight away, it works a treat by the looks of it.

Thanks again.

Hi Brian
It's not a space at the end of the file.  Instead it's a character 0.  Not 
entirely sure why Jaws 14 is adding this in but I'm sure people with far 
greater knowledge than myself can let us know.  Perhaps there's a compiler 
directive that is required to make the string concatenation behave in a similar 
way to earlier Jaws versions.

Anyway all you need to do is to call Jamal's function and replace the character 
0 characters with empty strings e.g.

StringToFile (StringReplaceSubstrings (temp, "\0", ""), "c:\\temp\\test.txt")

Hope this helps

Cheers

Subject: [jawsscripts] Problem with StringToFile, Jamal's HSL

Hi
I have a problem which is baffling me at the moment. For various projects 
available to the community, I use Jamal's Homer Script Library. It is full of 
useful functions and I've used it for years.

However there is one function which is causing a problem. It works fine with 
many jaws versions up to and including 13, but it does not work correctly in 14 
and I do need it to if anyone can please suggest a solution.

The function, StringToFile, writes a string to a text file. In jaws 14, this is 
working fine except that it leaves an extra space character at the end. This 
can be simulated simply as follows:

Assume that homer.jsb is attached via a use statement to your script.

Script test700 ()

saystring ("ok")

var

string temp

let temp = "hello "

let temp = temp +"goodbye"

StringToFile (temp, "c:\\temp\\test.txt")

ã

ã

EndScript


This outputs to a text file "hello goodbye", then a space character, rather 
than just having a clean file.

Does anyone have a suggestion as to how I may erase the space character?

Thank you.

Brian Hartgen
