How the new INCLUDE statement works...

This is my take on how the new INCLUDE statement works in 4.50 ... works just like the CALL statement, except that if your tokenizing a script, it will "embed" or "include" these external scripts inside the generated KX (tokenized) script itself, by way of example:
1) Create a script called SUB.KIX that contains the following:
SUB.KIX
$X = 100
$Y = 200
2) Create a "mainline" script called MAIN.KIX that "uses" this external script, will use the CALL statement for this first example:
MAIN.KIX
break on
call "sub.kix"
?"x=" $X
?"y=" $Y
3) If you just run the mainline script, you would get this expected result:
C:\>kix32 main.kix
x=100
y=200
4) Now, change the CALL statement in MAIN, to be an INCLUDE statement, and run it again (the same result, INCLUDE is like a CALL):
MAIN.KIX
break on
include "sub.kix"
?"x=" $X
?"y=" $Y
C:\>kix32 main.kix
x=100
y=200
5) Now here is the neat part, tokenize MAIN.KIX into MAIN.KX, like this:
C:\>kix32 /t main.kix
6) Then run MAIN.KX and you get this:
C:\>kix32 main.kx
x=100
y=200
7) Now - the really cool part, delete (or rename away) the original SUB.KIX file, the MAIN tokenized script still works because SUB.KIX is "part of" (it's been included into), MAIN.KX, like this:
C:\> ren sub.kix sub.tmp
C:\> kix32 main.kx
x=100
y=200
If you ran the original (untokenized) MAIN.KIX again, it would fail, because SUB.KIX is not there !
Here's more, been doing much testing with using FUNCTION calls in INCLUDED scripts, and I am getting nasty Kixtart crashes - so think Ruud had some more work to do with functions in included files.

I am interested to see what INCLUDE does. CALL, I am seeing some behaviors where VARs are not be passed to CALLed scripts. I will have to test and see.

Maybe I am a bit asleep here..
Did some testst with this:
Code:
IF RIGHT(@SCRIPTNAME,2)='kx'
INCLUDE @LDRIVE+'newscript\function.kx'
ELSE
INCLUDE @LDRIVE+'newscript\function.kix'
ENDIF
Results:
Quote:
ERROR : expected string!
Script: \\<DC>\netlogon\newscript\kent\kixtart.kix
If I change it to (I know VARS in strings are evil):
Code:
IF RIGHT(@SCRIPTNAME,2)='kx'
INCLUDE '@scriptdir\function.kx'
ELSE
INCLUDE '@scriptdir\function.kix'
ENDIF
Results:
Quote:
ERROR : failed to find/open script ["]!
Script: \\<DC>\netlogon\newscript\kent\kixtart.kix
Thanks,
Kent

This is an invitation to write new and/or publish an existing KiXtart script that is the equivalent of 'make'
Not at all.
"Make" is a generic project management tool, and handles KiXtart files perfectly well.
When Ruud first proposed the INCLUDE statement I posted details of how to use "make" to generate monolithic scripts suitable for tokenising. Can't find the blasted post now however.
