Concatenation addition to the Help File

[Anonymous]

To the keepers of the new Help File:

Under the heading of String operations, you might want to list the concatenation operator (plus) as an option.

I ended up using string concatenation a fair amount in the Sine and Cosine routines I posted a little earlier. I wasn't sure if it was in the language, but I just went ahead and tried it, and there it was! And it works as expected.

There really are lots of Easter eggs in GC Basic...

Another learning. I wonder what the constraints are.

I have added the following to the Help File. I will publish to the web next week.

Concatenation

Syntax: 
    stringvar = variable1 + variable2

Command Availability:
    Available on all microcontrollers

Explanation:
    The method join two variables into another variable. 

    This method does not change the existing strings, but returns a new string containing the text of the joined variables.

    Concatenation joins the elements of a specified values using the specified separator between each variable. 

Example:

    timevariable = 999
stringvar = "Time = " + timevariable ' Returns Time = 999 

[Chuck Hellebuyck]

So the variables don't have to be string variables?
How does that work?
999 could be contained in a word or int which will use two bytes but 999 converted to a string requires three bytes. So is 999 converted to a string before being combined into a concatenated string variable?

[Anobium]

Both variables need to be strings.

StringVariable = str ( 999 ) + " works" ' works.

StringVariable = str ( bytevariable ) + " works" ' works.

StringVariable = stringvariable + " works" ' works.

I will update help file to clarify.
