As I recall, by default, you can have up to 1000 labels.  This can be 
changed with PFLBSIZE.

What do you mean by "how deep"?

The value of a label is set when that line is executed, and it retains that 
value regardless of any other processing that you run, unless/until you 
execute that line again.  As I recall, a label which has not been executed 
is "false".
