-/* "dynl.c" dynamically link&load object files.

-/* We should try to implement dynamic-link/dynamic-call for VMS,
- too. */

-#include "_scm.h"
-
-/* This permits dynamic linking. For example, the procedure of 0 arguments
- from a file could be the initialization procedure.
- (vms:dynamic-link-call "MYDISK:[MYDIR].EXE" "foo" "INIT_FOO")
- The first argument specifies the directory where the file specified
- by the second argument resides. The current directory would be
- "SYS$DISK:[].EXE".
- The second argument cannot contain any punctuation.
- The third argument probably needs to be uppercased to mimic the VMS linker.
