$IF <CONDITION1> ... $ELSEIF<CONDITION2> ... $ENDIF
This instruction analyzes the following programmed conditions.
• If <condition1> is true, it executes the blocks contained between $IF and $ELSEIF.
• If <condition1> is false, it analyzes <condition2>. If true, it executes the blocks contained
between $ELSEIF and $ENDIF (or the next $ELSEIF if any).
• If all the conditions are false, the execution continues at the block after $ENDIF.
As many $ELSEIF instructions as necessary may be programmed.
An $ELSE instruction may also be included. In this case, if all the conditions are false, it will
execute the blocks contained between $ELSE and $ENDIF.

N30...
N40...
N50 $ELSEIF P2==[-5]
N60...
N70 $ELSE
N80...
N90 $ENDIF
N100 ...
If P1 is equal to 1, it will execute blocks N30 through N40. The execution continues at N100.
• If P1 is other than 1 and P2 is equal to -5, it executes block N60. The execution continues
at N100.
• If P1 is other than 1 and P2 is other than -5, it executes block N80 and the execution
continues at N100.
