Minimum function on characters

[Gizmo]

Hello everybody,

Can someone give me an explanation about the following code:

define var VC_TEST as character initial "TEST" no-undo.

minimum(",", VC_TEST) ==> gives ","

minimum("|", VC_TEST) ==> gives "|"

I don't understand why the second function gives back the "|". This string is smaller than TEST??

Thanks,

Gizmo.

Oeps, my mistake.
I did have the question why it gives back TEST, because TEST is bigger then "|":u. Do you know why?

Sorry.

Function minimum sort chracter values like dictionary. First function compare first characters of two values. If they are the same finction will compare next characters.
In your example "T" is smaller then "|".
ASC("T") = 84
ASC("|") = 124
