hi all
i know it's probably an easy task but for some reason or another i just can't get it going right now when working with INCLUDED files

(maybe it's just to late, or early in the morning)
here's what i mean:
1):
i have the MAIN SOURCE FILE called "main.dba"
within this MAIN file of course i have some general startup code, etc.
2):
i then ADD another file under the INCLUDED SOURCE FILE & named it "level1.dba"
within this source file would be "Level 1" & asociated code, etc.
3):
now, what IF i continued adding additional source files (level2,dba, level3.dba, etc)
4):
THE PROBLEM:
how do i from the MAIN file call these INCLUDED SOURCE FILES and then get back to the MAIN file safely?
i have tried this:
#include "level1.dba"
level1 ()
etc.
nothing works. it is late but if anyone could tell me, or better yet make a quick example that calls diferent INCLUDED FILES would be great. i know it cant be that hard of a thing....is it?
thanx in advance
