Dear Sirs,

I've got a long list of Tag with same type and different names, I need something similar to Screen Window Tag prefix, but in a C script.

i.e.

SetTagWord("Prefix_Var017", value );

SetTagWord("Prefix_Var018", value );

SetTagWord("Prefix_Var019", value );

How can I edit Prefix to obtain:

SetTagWord("MyPrefix_Var017", value );

...

this  seems to work, but I need a tag_prefix tag for every real tag that need to be managed:

strcat(tag_prefix, "_Var016");

SetTagWord(tag_prefix, value  );

would it be possibile something like this? if yes how?

SetTagWord(tag_prefix + "_Var016", value  );

 I'm using

I think you are looking for & (ampersand) not +

also you may need FormatNumber(TempInt,"000") Can't find documentation on that, but it compiles.. It should take the integer in TempInt and format it to be 3 digits padded on the front with 0's.

So:

  5 -> 005

 15 -> 015

215 -> 215

Thank you for the answer, so no other way than

I cannot use vba because it cannot work within Archives... only C can.

It's just an hope, maybe  adding python at the list of scripting language can make some developer work with siemens software...

in python I would do this with just one line:

SetTagWord( "{prefix}_Var016".format(prefix='MyPrefix'), value )
