IMPORT with list of C-Extensions

The IMPORT instruction for C extensions denies a comma-separated syntax.

Before version 2.21.00, the IMPORT instruction for C extensions was documented as allowing a comma-separated list of libraries:
IMPORT lib1, lib2

This compiled, but at runtime only the first library was found. Using elements of the other libraries raised a runtime error.

With 2.21.00 and the new .42m module importation support, the compiler is now more strict and denies the comma-separated syntax. You must specify every library, Java class or .4gl module in separate lines:
IMPORT lib1
IMPORT JAVA myclass
IMPORT FGL mymodule
