you dont have to use a #define directive. Use the "@". If file test.inc
contains common block definitions, just put the following command in each
file that needs the common blocks:
@test.inc
Be sure that the "@" is in the first column of the program file.

try using keywords and the KEYWORD_SET() logical function.
