Module declaration not permitted.
#2140 Compile-time error
Module declaration not permitted.
Additional Information
Module declarations can only occur at the beginning of a module file.
Explanation
A module declaration was found somewhere other than the first line
of OmniMark code in a file imported as a module. The most common
cause of this error is specifying a module file after the -s
command-line option instead of a main program. Modules can only be
used by importing them into the main program.
