LEFT$ Function

Purpose:

To return a string that comprises the left-most n characters of x$.

Comments:

n must be within the range of 0 to 255. If n is greater than LEN(x$), the entire string (x$) will be returned. If n equals zero, the null string (length zero) is returned (see the MID$ and RIGHT$ substring functions).

Example:

20 B$=LEFT$(A$, 3)
30 PRINT B$
