low( type or variable ) : Ordinal Type;

 

Returns the lowest allowed value of either a type or a variable of that type. It would typically be used in conjunction with arrays and, for arrays, it returns the lowest index value in that array.

 

Parameters

 

 

type

  TArray = array[0..10] of Integer;

 

  low(TArray) would return 0 since 0 is the lowest allowable index in that array type.

 

 

Important!: It is critical that you do not confuse this Pascal low() utility function with the low price of a data series. When customizing a user script, always use Symbol.low() rather than just low(). Not paying attention to this can cause errors that are difficult to debug.
