Can we concatenate a string with other string or with any value?

i have a folder which stores my waves which are named with the help of this command UniqueName("Wave",1,0) and after some personalizing i have made a function which plots the graph in host panel with NewImage /Host=# root:folder1:'Filename'

but i am controlling the files to select using panel to select which wave to plot an image for;

controlInfo provides me the wave number

and accordingly my Filename should be something like this Filename=Wave+V_Value

how can I pass it to the NewImage/Host=# root:folder:'Fiilename'

 

You can concatenate strings by just adding strings together:

String combined = "Hello" + " " + "World"

This can also be used to add strings from a (user or built-in) function which outputs strings:

String combined = "Hello World" + ", version " + num2str(2)

I guess, that you need something like:

Wave myinputwave
String Filename = nameofwave(myinputwave) + num2str(V_Value)

For more information you might want to read:

You then may need the $ symbol to convert a string to a reference for use as literal name, but I am not completely sure where you want to use this. Do you want to generate a name which can identify some host window? There might be better ways to do this like, for example, working with a generated list of open windows or directly from the calling function if it is a control within said window.
