  moved down in program memory
To go to a line in a very long program, that is, longer than 999 lines, you press EEX in place of the thousands digit. You then key in the three remaining digits of the line number. For example, to go to line 1,540 of an 1,800 line program, simply press g GTO · EEX 540. This long-program addressing is only useful when yor HP-41C has been enhanced with memory modules extensions.
  g GTO · EEX 540 = go to line 1540
Specifying a line number for GTO · that is larger than the current program will simply set the calculator to the END of that program.
Running the Modified Program
To run the modified AREA program, you have only take the calculator out of PRGM mode and, since the calculator is still in USER mode, simply press the LOG key (remember that you assigned AREA to the LOG key location for execution in USER mode).
Run the modified AREA program for values of 78″ (height) and 14″ (radius):
