If it is still filename.kix.txt then just save it as .TXT, goto DOS or explorer and rename the file to .KIX and re-open it in notepad.

Instead of Notepad, I use TextPad by Helios Software. Have a look here. There are plenty of other programs like it. TextPad colours the KiX commands and functions making it easier to read.

Instead of

break on
$a="123x"
$b=val($a)
$a ?
$b ?
if $a=$b
"equal"
else
"not equal"
endif
?

It looks more like

code:

---

break on

$a="123x"
$b=val($a)

$a ?
$b ?

if $a=$b
	"equal"
else
	"not equal"
endif

?

p.s. I am not affiliated with Helios Software yada yada yada...
