result
* If you omit the input parameter that connects to InN, the default value is not applied, and a building error will occur. For
example, if N is 3 and the input parameters that connect to In1 and In2 are omitted, the default values are applied, but if the
input parameter that connects to In3 is omitted, a building error will occur.

In1 to InN
Out OK
Function
The EQascii instruction determines if from two to five text strings In1 to InN are all equivalent. If the are
all equivalent, comparison result Out changes to TRUE. Otherwise, the value of Out is FALSE. "Equiva-
lent" means that both the lengths and contents of the text strings are the same.
The following example is for when In1 is "A", In2 is "AB", and In3 is "ABC". The value of variable abc will
be FALSE.
