Call Keyword 2

[Morpheus1981]

I 've looking for a clear explanation of "Call" keyword. But I still don't understand what is it exactly for?
Can anyone tell why should I use Call keyword before a sub?
How can use it? Does it do something? I have made many tests and I no see difference between using it and don't use it...
Advise me please

"...You are not required to use the Call keyword when calling a procedure. However, if you use the Call keyword to call a procedure that requires arguments, argumentlist must be enclosed in parentheses. If you omit the Call keyword, you also must omit the parentheses around argumentlist. If you use either Call syntax to call any intrinsic or user-defined function, the function's return value is discarded."

I think the that the only one difference between that you can simply reject the return value.
..++ or with parantheses the calling is more separable

The return value is discarded in either case because in either case (with or without CALL keyword) it is still a "Call" just like
X = 1
and
Let X = 1
are both Lets.
The only difference is syntax.
