NEascii
NEascii
The NEascii instruction determines if two text strings are not equivalent.
* If you omit an input parameter, the default value is not applied. A building error will occur.
The NEascii instruction determines if two text strings In1 and In2 are not equivalent. If they are different,
comparison result Out will be TRUE. If they are the same, comparison result Out will be FALSE. “Equiv-
alent” means that both the lengths and contents of the text strings are the same.
The following example is for when In1 is “A” and In2 is “AB”. The value of variable abc will be TRUE.
