Unit System Category string handling routines function Pos(Substr: string; S: string): Integer; Description Pos searches for a substring, Substr, in a string, S. Substr and S are string-type expressions. Pos searches for Substr within S and returns an integer value that is the index of the first character of Substr within S. Pos is case-sensitive. If Substr is not found, Pos returns zero. | Цитата: Returns a substring of a string or a segment of a dynamic array. Unit System Category string handling routines function Copy(S; Index, Count: Integer): string; function Copy(S; Index, Count: Integer): array; Description S is an expression of a string or dynamic-array type. Index and Count are integer-type expressions. Copy returns a substring or sub array containing Count characters or elements starting at S[Index]. If Index is larger than the length of S, Copy returns an empty string or array. If Count specifies more characters or array elements than are available, only the characters or elements from S[Index] to the end of S are returned. Note: When S is a dynamic array, Copy can only be used as a parameter in a call to a procedure or function that expects an array parameter. That is, it acts like the Slice function when working with dynamic arrays. | |
