Pascal Syntax Error

问题

I have the following function in my program:

function Getrand(rStart,rEnd:Integer): Integer;
var
diff: Integer;

begin
diff := rEnd - rStart;

Getrand := Random(diff) + rStart;
end;

When I try to compile the program, I get this error:

Failed when compiling
Line 27: [Error] (27:9): Invalid number of parameters in script 

What am I doing wrong?

回答1:

Perhaps your flavour of Pascal doesn't support the traditional return value syntax. Try Result := … instead of Getrand := ….

回答2:

you can use

Exit(Random(diff) + rStart)

instead. But keep in mind that if you do that it will exit from function after returning the value.

回答3:

You need to write Getrand(Random(diff),rStart); to send variables to function
