Example of Use
Here’s the creation of the object file called mystro.
run $data01.toolsy02.ccomp /in mystrngc /mystro;suppress

Build the DLL and the Program
First we build the DLL, then the main executable file called revstr. It has to be in that
order because the main executable could not refer to a DLL that did not yet exist. (If
the linker’s -allow_missing_libs option is specified, the main executable could be
linked befoe the DLL is linked.)
Note that the -lib option references the DLL called mystrdll. Note the -export_all
option. We could also individually reference the items to be exported, as follows:
-export StrRev
Note the -shared option sent to eld. This creates the DLL. The -dll option can be
used to do the same task, and is probably more descriptive of what we want to
achieve. Either option can be used.
