Security using Function

Another effective variant to add security to a program is by using a Function. Function can be of the types f-cando(“xe-dev,xe-javra”) and lookup(xprog.xptyc, “RE,RE-1024″) > 0 .

Here in f-cando(‘xe-dev,xe-javra’) – f-cando refers to the name of the function that will allow the user an access to copy feature – ‘xe-dev, xe-javra’ refers to the name of 2 users/ user groups that are allowed to access this copy feature.
