<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">My guesses:
1) Yours. Perhaps pbx_builtin_getvar_helper did not exist.
2) This may have been used to get multiple variables. The loop was reduced more and more until it was only grabbing one variable.
Either way, pbx_builtin_getvar_helper makes it much easier here.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">3) The code was copied directly out of another channel that retrieved multiple variables, and the author knocked it down to just retrieve this one, not knowing the pbx_builtin_getvar_helper() is far easier. pbx_builtin_getvar_helper() first appeared in version 0.3.0, and this ALERT_INFO variable was not added until a later version.</pre>
