- * Duplicates the Basic string functions Left$, Right$, and Mid$ *
- *****************************************************************
-
- A very simple unit to assist in parsing strings using familiar
- Basic commands. StrName is self-explanatory. NumChars is the
- length of the string to be returned, and StartPos is the index to
- start at for the Mid$ (aka MidStr) function.
-
- Released into the public domain, I hope someone will: a) find it
- useful, and b) add support for comma-delimited and space-delimited
- input (a la Basic).

- Flames may be directed to the NUL device. :)

- Unit BasicStr;
-
- Interface
-
- Function MidStr ( StrName: String; StartPos, NumChars : Integer) : String;
- Function LeftStr ( StrName: String; NumChars : Integer) : String;
- Function RightStr( StrName: String; NumChars : Integer) : String;
-
- Implementation
-
- Function MidStr;
- Begin
- MidStr := Copy ( StrName, StartPos, NumChars);
- End; {Mid$}
-
- Function LeftStr;
- Begin
- LeftStr := Copy ( StrName, 1, NumChars);
- End; {Left$}
-
- Function RightStr;
- Begin
- RightStr := Copy ( StrName, ( Length(StrName) - (NumChars - 1)), NumChars);
- End; {Right$}
-
- End. {Unit}
