Precautions for programming
● Always use the INTPG n and IRET instructions in combination. A syntax error occurs if either
"INTPG" instruction or "IRET" instruction is not used.
● More than one INTPG instruction with the same number cannot be specified.
● If a unit in which interruption occurs is not installed in a specified slot number, the no target
unit error 10 is displayed and the mode cannot be switched to RUN.
● Branching from the interruption program area (between INTPG and IRET) to other
subprogram areas or main program area is not possible.
● A subroutine program cannot be used in an interrupt program.
● An interrupt program cannot be used in a subroutine program.
● It is operable even if one IRET instruction is used for multiple interruption programs INTPG.
