Sample = MyPtr^(1, 2, 3) ‘ Perform function call via pointer, call Func1, the return

value is 3

MyPtr = @Func2 ‘ MyPtr now points to Func2

Sample = MyPtr^(1, 2, 3) ‘ Perform function call via pointer, call Func2, the return

value is 5

MyPtr = @Func3 ‘ MyPtr now points to Func3

Sample = MyPtr^(1, 2, 3) ‘ Perform function call via pointer, call Func3, the return

value is 0

end.

@ Operator

The @ operator constructs a pointer to its operand. The following rules are applied to @:

- If X is a variable, @X returns a pointer to X.

Note: If variable X is of array type, the @ operator will return pointer to it’s rst basic element, except when the left

side of the statement in which X is used is an array pointer.

In this case, the @ operator will return pointer to array, not to it’s rst basic element.

program example

dim w as word

ptr_b as ^byte

ptr_arr as ^byte[10]

arr as byte[10]

main:

ptr_b = @arr ‘ @ operator will return ^byte

w = @arr ‘ @ operator will return ^byte

ptr_arr = @arr ‘ @ operator will return ^byte[10]

end.

- If F is a routine (a function or procedure), @F returns a pointer to F.
