*Conan The Librarian
/COPY_SOURCE (D) /NOCOPY_SOURCE Controls whether a copied source file is created in the current program library when a compilation unit is compiled without error. The ACS RECOMPILE command requires that a copied source file exist in the current program library; the ACS COMPILE command uses the copied source file if it cannot find an external source file when it is recompiling an obsolete unit or completing an incomplete generic instantiation (see Developing Ada Programs on OpenVMS Systems). Copied source files may also be used by the OpenVMS Debugger (see the Developing Ada Programs on OpenVMS Systems for more information on debugging tasks; and the OpenVMS Debugger Manual for more information on the debugger). By default, a copied source file is created in the current program library when a unit is compiled without error.
