Remarks
When executed, USES search for a module name starting with "thinBasic_" plus the string passed as parameter plus ".dll".
For example,
USES "Console"
will search for "thinBasic_Console.dll" file name.
USES will search for the requested module following below path sequence:
1. Source script path
2. Source script path + Lib
3. Source script path + Bin
4. Source script path + Mod
5. Source script path + Lib + "thinBasic_" + ModuleName
6. Source script path + Bin + "thinBasic_" + ModuleName
7. Source script path + Mod + "thinBasic_" + ModuleName
11. thinBasic path
12. thinBasic path + Lib
13. thinBasic path + Bin
14. thinBasic path + Mod
15. thinBasic path + Lib + "thinBasic_" + ModuleName
16. thinBasic path + Bin + "thinBasic_" + ModuleName
17. thinBasic path + Mod + "thinBasic_" + ModuleName
If none of the above will be valid, a runtime error will be generated.
