Returns the string N times evaluated.
$eval(string,N)
If N isn't specified, N is set to 1.
Example:
var %var = m00 var %string = % $+ var
Now echoing %var would echo "m00" and echoing %string would echo "%var"
echo -a $eval(%string,0)
This would echo "%string" since %string is not evaluated.
echo -a $eval(%string,1)
This would echo "%var" since %string is evaluated once. Notice that this is the same as echoing %string
echo -a $eval(%string,2)
This would echo "m00" since the string is first evaluated to %var and %var is then evaluated to m00
