LEFT$ Function
Purpose:
To return a string that comprises the left-most n characters of x$.
Syntax:
LEFT$(x$,n)
Comments:
n must be within the range of 0 to 255. If n is greater than LEN(x$), 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:
10 A$="BASIC"
20 B$=LEFT$(A$, 3)
30 PRINT B$
RUN
BAS
The left-most three letters of the string "BASIC" are printed on the screen.
