This parameter represents the rightmost position of the string-argument. <br /> <br /> The length may be a numeric constant, a single-element numeric variable, a numeric array element, a numeric expression, or a numeric function. This parameter represents the number of characters to be returned by the RSUB function. <br /> <br /> Also see SUB. <br /> <br /> '''Example 1:''' ZIP$ = RSUB(ADDRESS2$,1,5)<br /> <br /> This example uses the RSUB function to return the last five characters of data from the variable named ADDRESS2$. The position is set to 1, indicating the right side of the string-argument. The length is set to 5, indicating the number of characters to be returned by the RSUB function. <br /> <br /> If the value of ADDRESS2$ equals &quot;Sebastopol, CA 95472&quot;, then the value of ZIP$ will equal &quot;95472&quot; -- the righthand 5 bytes of the field. <br /> <br /> '''Example 2:''' IF RSUB$(ADDRESS2$,1,5) = &quot;95472&quot; THEN PRINT (0) &quot;Sebastopol&quot;<br /> <br /> This example shows how the RSUB function can be used in-line with an IF statement. In this case, the RSUB function returns the last five characters of the variable named ADDRESS2$ (see Example 1 above).</div>
