Get the next letter

[Jimakos]

Hello. My problem is something that should be a simple thing. I just need a calculation to give me the next letter from the one endeared on an other field. "a" on the first field, "b" the result of the calculation. I have tried "substitute" and "case" giving all the possible solutions, but I don't like it. Is there an other way?

Try something like:

Let ( [

alpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZ" ;

pos = Position ( alpha ; Character ; 1 ; 1 )

] ;

Middle ( alpha ; pos + 1 ; 1 )

)

Thank you very much. It was really helpful. I actually wanted to make a self join relationship that shows on a portal, the names starting with the letters on a global field. This was really easy (Table1:G_name <= Table2:Name), but it showed all the names from that point to the last. I wanted an "AND" relationship that finds the names from the next letter and upwards (Table1:G_name_low > Table2:Name)but I couldn't find the way to calculate the field G_Name_Low. The hard part was the one you helped. Thanks a lot..

Shouldn't there be a Propper( in there?

Code( and Char( does the same under fm10:

Char(Code("a")+1) gives b

You need to study this template:

No need of Proper. Everything is in capital letters. I show the demo. I'll study it. But I thing this is easier:

Case(

G_Name = " "; "Ё";

Let([

char = Right (G_Name ; 1);

word = Left (G_Name ; Length (G_Name)-1);

all = "ΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩЁ";

pos = Position(all;char;1;1);

next = Middle(all;pos+1;1)

];

word & next)

)

This is the G_Name_Next field. Sorry for the Greek. It's a Greek program anyway :

Just had a problem with the last letter of the alphabet, but solve it using the next letter of unicode. And " " and "Ё" is used on global fields to list all the names.

Wouldn't the same thing be accomplished simply by making the relationship < instead of ≤ ?

What for? Position() is not case-sensitive.
