You are correct; access to array optionVars is a bit limited.
To access the n'th item in an optionVar:
int $byIndex = 3;
string $indexed = "";
string $vars[] = `optionVar -q stringArrayOptionVar`;
if ( ( $byIndex >= 0 ) && ( $byIndex < `size $vars` ) )
{
$indexed = $vars[$byIndex];
}
To set the n'th item requires rebuilding the optionVar:
string $vars[] = `optionVar -q stringArrayOptionVar`;
if ( ( $byIndex >= 0 ) && ( $byIndex < `size $vars` ) )
{
$vars[$byIndex] = "value";
}
optionVar -clearArray stringArrayOptionVar;
// <or> optionVar -remove stringArrayOptionVar;
for ( $item in $vars )
{
optionVar -sva stringArrayOptionVar $item;
}
