NJ-series Instructions Reference Manual (W502)
These instructions search Size elements in an array of structures In[]. The search range is therefore
from In[0] to In[Size
− 1]. The instruction searches member to search Member in the structures.
One of the members to search in the elements of In[] is passed as an argument to Member. The ele-
ment number of the element with the maximum or minimum value is assigned to InOutPos[0] and the
number of elements that were found is assigned to Num. If more than one element was found, the ele-
ment number of the lowest element with the maximum or minimum value in In[] is assigned to InOut-
Pos[0].
Always attach the element number to input parameter that is passed to In[], e.g., array[3].
z RecMax
The RecMax instruction searches for the maximum value. The maximum value of the member to
search is assigned to search result Out.
z RecMin
The RecMin instruction searches for the minimum value. The minimum value of the member to search
is assigned to search result Out.
The following example shows the RecMax instruction when Size is UINT#5.
