  h <- function(a=1,b=3,c=3) {cat("--h--");paste("h(a,b,c)=",a+b+c)}
  ## create functions
  gg <- makeWidgetCmd("Hay it is g !!",g,GRAB=FALSE)
  hh <- makeWidgetCmd("Hay h here !!",h,GRAB=FALSE)
  ## calling them
  gg()
  cat("\nClose it before calling hh(), they sharer parameters a and b!!")
  hh()
  ##
  ##  simple example(continuation)
  ##
  ## to be able to use both at the same time:save info for h in other place
