Function
The ArySearch instruction searches Size elements of one-dimensional array to search In[] for elements
with the same value as search key Key. The search starts from In[0].
The values of search result Out, found element number InOutPos, and number found Num are as fol-
lows:
Element with
same value as
Key
Exists.
Does not exist.
The relationship between values with data types that are not integers or real numbers are determined
as given in the following table.
Data type
TIME
DATE, TOD, or DT
The following example is for when Size is UINT#6 and Key is INT#5555.
The input parameter that is passed to In[] is abc[2], so the search starts from abc[2].
LD
abc[2]
UINT#6
INT#5555
def
The lowest element number that
contains same value as Key is 3.
In[0]=abc[2]
In[1]=abc[3]
In[2]=abc[4]
Size=UINT#6
In[3]=abc[5]
In[4]=abc[6]
In[5]=abc[7]
Additional Information
When you compare TIME, DT, or TOD data, adjust the data so that the precision of the values is the
same. Use the following instructions to adjust the precision of the values: TruncTime (page 2-651),
TruncDt (page 2-655), and TruncTod (page 2-659).

Out InOutPos
TRUE Lowest element number that con-
tains the same value as Key
FALSE Does not change.
The numerically larger value is considered to be larger.
Later dates or times of day are considered to be larger.
