How does "Position" in a character string work? July 12, 2009 10:26PM |
I have tried ...
StartLocation is an int = Position(MyString, "Delivery", 0, FromEnd)
Info(StartLocation)
and ...
StartLocation is an int = Position(MyString, "Delivery", 1, FromBeginning)
Info(StartLocation)
Both give StartLocation a value of 1730 which is wrong, both times...
I have tested the length of the string using ...
Info(Length(MyString)) (which is 2366)
AND I have searched the string to verify the word "Delivery" is only located in the string one time
This code gives me the exact data I need:
===================================
FirstCut is a string = Right( MyString , 624)
EDT_Edit2 = Left(FirstCut, 191 )
===================================
I thought ...
StartLocation is an int = Position(MyString, "Delivery", 1, FromBeginning)
would give me the position of the letter "D" in delivery?
I guess I am not reading the help correctly, or at least not understanding ...
The complete string is below ...
Any help is greatly appreciated ... Dan

I've always had more luck (?!) with PositionOccurrence rather than Position. Don't know why - it's just always worked better for me and completely consistently in contrast with Position which gives me results I don't understand like the ones you have in your example.
Just my observation.
