Write and set string of different length in input

Write and set string of different length in input

Hi everyone,

I'm pretty new about Zenon programming and for sure I've some difficulties in developing new application from scratch but, in any case, I'm trying to improve my skill by reading the manual and by doing.
At the moment I'm working on an application that has to read and write a STRING (max length of 8 char) on the driver; for doing the writing operation, I'm using "Dynamic Texts" with the option "write set value" set to Active and actually I'm for sure able to insert a string by using the screen keyboard without the (redundant in my case) dialogbox.
The problem is that the string I'm trying to pass to the driver is of variable length and any time I put something smaller than the previous value, it memorizes the "merging" of the two strings.
Example:
I wrote "12345678" and the interface write the set value. After, I inserted "abc" and the result on that variable (that is always the same and defined as a string) is "abc45678" both on variable and on the input screen, instead, what I wanted, was only "abc".

I hope my problem is clearly explained and I hope also that somebody could kindly help me to solve this tricky issue. Thanks a lot in advance!
