+
+;; The only non-common lisp functions used in this file are in this section.
+;; The following functions are provided:
+
+;;   OsRunProgram program &rest args  
+;;      Run the named program with given arguments.
+;;      All I/O is to the current places.
+;;      Value returned is implementation-dependent.
+
+;;   OsRunProgramToStream program &rest args
+;;      Run the named program  with given arguments.
+;;      Input and error output to the current places.
+;;      Value returned is a stream of the program's standard output.
+
+;;   OsEnvVarCharacter
+;;      The character which indicates OS environment variables in a string.
+;;      On Unix this is "$".
+
+;;   OsEnvGet name
+;;      name is a string or a symbol
+;;      The string associated with the given name is returned.
+;;      This is from the environment on Unix. On CMS globalvars could be used.
+
+;;   OsProcessNumber
+;;      Returns a unique number associated with the current session.
+;;      On Unix this is the process id.  
+;;      The same workspace started a second time must give a different result.
