Description

Returns the substring of a specified length that appears at a specified position in a string.

MidStr returns a substring Count characters at AText[AStart].

If AStart is larger than the length of AText, MidStr returns an empty string.

If Count specifies more characters than are available, only the characters from AText[AStart] to the end of AText are returned.

Note: If AText is an AnsiString and the current locale uses multi-byte characters, MidStr may return more than ACount bytes. To return a specific number of bytes, use MidBStr.
