What is the meaning of CHV(ChanalLine,"["&str(GroupNr)&&"]/CHName")

[Quadrangle]

Hallo

Well it seems to work, but I didnt find what && means? Difficult to search it.

 What means && ? Where is it written in the Help HTML ?

And what exactly is str doing (The Input is the Index of the Channel like:

GroupNr = GroupPropValGet(iCount+1,"index")

Thank You

Hi Quadrange

& concatenatea two strings to one string. It is described here:

Alternative you can use the plus + to combine two strings to one string.

STR converts a numeric value to a string. With the optional parameter you can format the string.

Hope that helps

Hi

Thank you, so

["&str(GroupNr)&"] makes a string like: ["five"] ; if the Group Nr is 5 ???

Hi Quadrangle,

Correct, although you need leading and trailing quote characters to complete the string:

"["&str(GroupNr)&"]"

If you use the "&" operator to concatenate, then you don't need the "str()" command to convert the GroupNr value to a string.
