When you want to look in BYTE series the VALUE variable must be dimensioned as a BYTE. When you want to look in INTEGER or WORD series the VALUE variable must be dimensioned as an INTEGER.

 

The LookDown function is the counterpart of the LookUp function.

Lookdown will search the data for a value and will return the index when the value is found. It will return –1 when the data is not found.
