Function Explanation
_8

The Find instruction takes the characters in In2 as key characters and searches for the position of
key characters in the string In1. For example, as In1 is ABCDEFGH and In2 is DE, the value of Out
is 4.

The search starts from the first character in the string In1.

If multiple In2 strings exist in In1, the value of Out is the position of the first In2 from the beginning of
In1.

Precautions for Correct Use
The input variables are not allowed to omit. An error will occur during the compiling of the software if the
input variables are omitted. But the output variable is allowed to omit.

Programming Example

The FIND_In1 string is 'AaBbCcDd' and the FIND_In2 string is 'Cc'. As FIND_EN is TRUE, the
value of Out1 is 5.
