It has the following characteristics and limits:
The subprogram may be nested up to 18 levels by other subprograms, but if a dead cycle is
made by the closed loop calling, an alarm will be issued by system. Therefore to execute the data
volume under the control, the allowable subprogram calling times are 100, and the subprogram
calling in the 1st level is disabled. Alarm will be issued for the instructions or network between SP
and END2, after SPE and before SP which can't be executed by system.
