In almost all cases, this occurs when a program’s length exceeds the maximum available space in RAM or a
defective function key. The solution for this problem is to shorten the active program, or replace the
function key membrane panel. Consult the separate PathMaster® Manual in the Operating Guide for more
information on altering a program.
Subroutine Error
A Subroutine error occurs if the path programs have not been loaded correctly into segment 1, 2 or 3 of
memory. During the Startup Sequence and after Program Selection the main program attempts to load the
current program from the segment memory. If the subroutine can not be found the following message is
displayed. Please refer to the PathMaster® Manual for more information about downloading.
Subroutine error. The subroutine is not
stored in segment 1, 2 or 3.
