Just by way of more example, here is a dir listing of the tokenized MAIN.KX file, using the CALL sub.kix statement (reference):

2005/02/25 01:38 PM 84 main.kx

Here is the dir listing of the tokenized MAIN.KX file, using the INCLUDE sub.kix statement:

2005/02/25 01:38 PM 122 main.kx

Its bigger because SUB.KIX is physically "part of" (included into), MAIN.KX.
