REACTE program instruction the error *Too many subroutine calls* cannot be processed. (See the STACK monitor command.) l The error-handling program can contain a RETURN instruction. When it is executed, the program tries to re-execute the instruction that caused the error. Note that this may cause an endless loop if the error continues to occur. l Before the error-handling program is entered, a DETACH instruction for the robot (logical unit number 0) is effectively executed. Thus, an ATTACH instruction must be executed for the robot before program control of the robot can resume.
l If a STOP, HALT, or PAUSE instruction is executed within the error-handling program, the original error message is output unless the error-handling program contains a REACTE instruction with no argument. l Unlike REACT and REACTI, execution of the REACTE error-handling program is never deferred because of priority considerations.
