Go Up to Error and Warning Messages (Object Pascal) Index

This error message occurs when a call to procedure or function gives less parameters than specified in the procedure or function declaration.

This can also occur for calls to standard procedures or functions.


program Produce;
var
  X: Real;
begin
  Val('3.141592', X);   (*<-- Error message here*)
end.

The standard procedure Val has one additional parameter to return an error code in. The example did not supply that parameter.


program Solve;
var
  X: Real;
  Code: Integer;
begin
  Val('3.141592', X, Code);
end.

Typically, you will check the call against the declaration of the procedure called or the help, and you will find you forgot about a parameter you need to supply.
