 RTParams is a private interface. 


INTERFACE RTParams;

 This interface provides access to the runtime arguments from the
   command line.  Command line arguments that begin @M3 are considered
   runtime arguments.  They are removed from the usual (argc, argv) list
   of arguments very early in initialization.  A runtime argument has the
   form @M3x or @M3x=y.  x is the name of the argument, y is its
   value, and x=y is the full argument.  If =y is missing,  is
   the argument's value. 


VAR (*READONLY*) NumParameters: CARDINAL;

 Parameters are indexed from 0 to NumParameters-1. 

PROCEDURE Nth (n: INTEGER): TEXT;

 returns the n-th full argument. If n is not in [0..NumParameters-1],
   NIL is returned. 

PROCEDURE IsPresent (n: TEXT): BOOLEAN;

 returns TRUE iff n is the name of a defined runtime argument. 

PROCEDURE Value (n: TEXT): TEXT;

 returns the value of the runtime argument with name n.  If n is not
   the name of a runtime argument, NIL is returned.  If n is the name of
   an argument that was specified as @M3n, the empty string  is
   returned. 

PROCEDURE RawValue (n: TEXT): ADDRESS;

 returns the C char* that corresponds to the value. 

PROCEDURE Init ();

 called by the runtime initialization code 

END RTParams.
