Siemens S7 Strings

Hi
I have a task whereby I have a DB which is a list of strings which are defined as STRING[25] and there are 100 strings.

I wish to be able to copy 2 strings based on the 'row' within the DB into a totally seperate DB which will display them onto the HMI

ie if i had ints 1 and 6 this would copy string 1 and string 6 into the other db into slots 1 and 2

I am thinking i will need a pointer to do this and am uncertain how to proceed

If possible use SCL, this makes it a lot easier...
Else you can make a function which uses 2 pointers (source and destination) to copy the strings with the blkmov function (SFC20).
There are a lot of threads about pointers...

i am looking into this

See example code attached. To make it easier to test, I've created a DB with the source strings in it, and another DB of the same size to contain the destination strings. You can copy any source string number into any destination string number.

Open the blocks folder online and then open DB6 to view the strings that have been copied.

Thanks for your input. I think i will be abl to chop it slightly to suit my purposes.

I dont think i am going to break my neck over pointers because i have been told the new s7 software due at the end of the year wont support stl at all (IEC only)

Cheers
