<br>
regarding your SNES-Tool one can specifiy at least three types of<br>
accuracy which force the code to terminate. I would like know how you<br>
have defined (and implemented) the following quantities:<br>

The definition of the quantity "stol" is already described on one of<br>
your manual pages. Would you also like to present a cite where to find<br>
those definitions?<br>
Thanks in advance,<br>
