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.]
