Replaces all occurrences of a substring within a string, using case-sensitive search.

Use ReplaceStr to replace all occurrences of the substring AFromText with the string AToText, within the string AText. ReplaceStr returns the string obtained after replacement.

Use ReplaceText to do a case-insensitive replacement.

Note: This function is designed for UnicodeString variables. To work with AnsiString variables, use the System.AnsiStrings.StringReplace function. To work with WideString variables, use the System.WideStrUtils.WideStringReplace function.

Note: Recursive replacement of substrings is not supported. This means that if the substitution of AToText results in a new match for AFromText, that match is not replaced.

ReplaceStr is the same function as AnsiReplaceStr.

The StringReplace function is a more general replacement routine, giving case-sensitivity options, as well as the option to decide whether to replace all occurrences or the first occurrence of the substring in the string.
