RecSearch
The RecSearch instruction searches Size elements in the 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
for members that match the search key Key.
One of the members to search in the elements of In[] is passed as an argument to Member.
If any matching elements are found, the value of search result Out changes to TRUE. The element
number of the matching element is assigned to InOutPos[0] and the number of matching elements is
assigned to Num. If there is more than one matching element, the element number of the lowest match-
ing element in In[] is assigned to InOutPos[0]. If there are no matching elements, the value of Out will be
FALSE and InOutPos[0] and Num will be 0.
Always attach the element number to input parameter that is passed to In[], e.g., array[3].
The data type of search method Mode is enumerated type _eSEARCH_MODE. The meanings of the
enumerators are as follows:
For a linear search, the search is performed in order from the first element of In[].
