What is the difference between a Sub and a Function?..

Answer / mukesh

A function accepts any number of parameters (possibly
zero), does something with them, and returns a value.
A subroutine is performs an action, but doesn't return a
value.

There are two differences between a function and a
subroutine:
A)How they are invoked. B)How they are accessed.

A function call has the following syntax ::function (arg1,
arg2, ...)
where: function -->Is the name of the function. arg1,
arg2, ... Are the arguments.

A subroutine call has the following syntax ::subroutine
(arg1, arg2, ... {outputfield|'format'})
where: subroutine -->Is the name of the subroutine. arg1,
arg2, ... Are the arguments.
{outputfield|'format'} Is the name of the output field or
its format.

In addition, on some platforms, the functions are available
immediately; whereas, the subroutines are available in a
special subroutine library that you must access.
