WP 34S solve an integral

Code:

...
RDP 05    // round to e.g. 5 decimal places
x≠0?      // if result does not round to zero
x<> L     // recall the original unrounded value
RTN

This way the solver always gets the exact function result, and only values below the (here) 5–digit threshold are rounded to zero so that the solver quits.

A beginners question:
Where in Barry's program

Code:


LBL A
STO 00      //Save target integral result desired
DROP        //Lower stack to get Upper/Lower solve guess bounds
SLV 00
RTN
ERR 20      //If solve fails to find a root show this error
LBL 00
 0
∫ 01      // ∫ from x to 0 = –∫ from 0 to x 
RCL+ 00   // 10 – ∫
RTN
LBL 01
x²
RTN

should I insert your lines ?
Many thanks for the help!
