Example of Use
The following command input creates the DLL:
run $data01.toolsy02.eld mystro -o mystrdll -shared -export_all
eld - TNS/E Native Mode Linker - T0608H01 - 26OCT04

eld command line:
\speedy.$data01.toolsy02.eld mystro -o mystrdll -shared -export_all

Now Build the Program
The next step is to create the loadfile (the whole program) by use of the linker.
ccplmain contains initialization code for the C and C++ run-time libraries. Your
version of that file will probably be located in $system.system.
ccplmain contains external references to errno and environ (which are defined in
ZCREDLL) and C_INT_INIT_COMPLETE_ , C_INT_INIT_START_ , and exit (which
are defined in ZCRTLDLL).
Note that each DLL must use an individual -lib option to be linked with eld. The
command syntax does not allow for a single -lib option followed by a list of DLLs, for
example: -lib zcredll, zcrtdll, mystrdll is not valid syntax.
