void

InstallShield 2026 » InstallScript Language Reference

Void is not a true data type, in the sense that a variable cannot be declared as type void. Void is only used in function prototypes to indicate that the function does not return a value, as in the following:

prototype void Subroutine(int);

function void Subroutine(int);

begin

// perform operations, but

// do not return a value

end;
