## Logical (YES/NO or ON/OFF) Options

Several options of commands are “logicals” which can have only one of 2 values: TRUE = YES, shown in the display as: T, or: FALSE = NO, shown in the display as: F. The command syntax and logic for ALL these options is the same, e.g., enter at the prompt PAKO > :

    OTFMAP /ZIGZAG          ! TURN OPTION  ON/TRUE/YES : T
    OTFMAP /ZIGZAG YES      ! TURN OPTION  ON/TRUE/YES : T
    OTFMAP /ZIGZAG .TRUE.   ! TURN OPTION  ON/TRUE/YES : T
    OTFMAP /ZIGZAG NO       ! TURN OPTION OFF/FALSE/NO : F
    OTFMAP /ZIGZAG .FALSE.  ! TURN OPTION OFF/FALSE/NO : F

[Note: the default value for some logical options, e.g., /ZIGZAG, is T; for other logical options the default is F.]
