type TSysCharSet = set of Char;
function WrapText(const StrLine, BreakStr: string; BreakChars: TSysCharSet; MaxCol: integer): string; overload;
function WrapText(const StrLine: string; MaxCol: integer = 45): string; overload;
Returns a string broken into multiple lines.
Each line of text in StrLine is broken when a line reaches MaxCol characters.
BreakStr is inserted in the string after a series of BreakChar characters at the end of the line, to create a line break.
If the BreakStr and BreakChars parameters are omitted, WrapText searches for space, hyphen, or tab characters on which to break the line and inserts a carriage return/line feed pair (#13#10) at the break points.

//s=BreakStr is inserted in the
