Optional parameters initialization

Hello Joan,

unfortunately it is not possible to initialize optional parameters in RAPID on declaration level.
Anyway I think this would be useless because (in contrast to some other laguages) from inside the routine
the parameter is simply NOT present when called without passing an appropriate argument.
So you can't use it at all if not present (Runtime error when accessing the param)

You can work around this with a second variable:

PROC SetVel(num nC, num nH, num nV, \bool b1)


  var bool bArg1 := TRUE;                      ! initialize with default value
  if Present(b1) bArg1 := b1;                 ! overwrite with parameter if present


  ! use bArg1 instead of b1 in the routine....


ENDPROC
