String Parameters

When you declare routines that take short-string parameters, you cannot include length specifiers in the parameter declarations. That is, the declaration procedure Check(S: string[20]); // syntax error causes a compilation error. But type TString20 = string[20]; procedure Check(S: TString20);

is valid. The special identifier OpenString can be used to declare routines that take short-string parameters of varying length:

procedure Check(S: OpenString);

When the {$h} and {$p+} compiler directives are both in effect, the reserved word string is equivalent to OpenString in parameter declarations.

Short strings, OpenString, $h, and $p are supported for backward compatibility only. In new code, you can avoid these considerations by using long strings.
