 Keep in mind that to support ''#IFEXT'' as an optional extension, an '':IFEXT'' label SHOULD be provided to handle the situation in which this extension is not present. Keep in mind that to support ''#IFEXT'' as an optional extension, an '':IFEXT'' label SHOULD be provided to handle the situation in which this extension is not present.

 +#ifext 00000000 0001 zap touch
 +:ifext
 +#end
 +:touch
 +I found nothing...
 +#end
 +:touch
 +I found IFEXT support!
 +#end
 +</code>

 +==== Two touch codepaths (#BIND workaround) ====
 +
 +If the code above is bound, '':TOUCH'' might end up being zapped multiple times. This code takes care of that:
 +
 +<code>
 +@Interactive
 +#send init
 +#end
 +:init
 +#ifext 00000000 0001 zap touch
 +:ifext
 +#end
 +:touch
 +I found nothing...
 +#end
 +:touch
 +I found IFEXT support!
 +#end
 +</code>
 +
 +An alternative, more advanced technique is pre-setting the instruction pointer in an external editor.
