Fortran static common blocks and PL/I static external data of the same name can be shared among routines in a load module under the following conditions:

• The Fortran static common blocks are either used only with one load module in an application or they are declared as private common blocks. A private common block is not shared across load modules and is created in any of the following ways:
  • Specified or implied by the PC compiler option
  • Referenced by Fortran object code produced by the VS FORTRAN Version 2 Release 4 compiler or earlier
  • In an application that executes with the PC runtime option.
