Given that this trick works though it must parse form the top and the first instance of LBL 01 is acted on. It leads me to wonder if the program is parsed top to bottom each time a local label is used or if the first time a label is encounter its address is stored somewhere and accessed by index. More reading to do.

The calculator scans the source code, searching for the given local label, from the position of the program counter (containing a GTO ou EXQ instruction) down to the first occurrence of the label.
