Palabras Reservadas

Las palabras reservadas del Cobol, son aquellas que el propio compilador utiliza y por lo tanto no podemos utilizar como variables en nuestros programas. Estas han ido avanzando con el paso de los tiempos y cada compilador incluso, incluyendo nuevas. Aquí voy a poner una lista de la cantidad mayor que pueda.
