Backslash during text handling

Posted on by Ding_Zhang

I have searched but not found relevant post.

I am composing the Windows file path with "Set variable" action in Power Automate Desktop. However, I found that once I use backslash mark, it generate syntax error.

I have two string variables. One is the basic path. Another one is the remaining part of the path, which is dynamic. I need to "concatenate" them together. Therefore I use "set variable" action and write as following.

%OneVariable + 'abc' + AnotherVariable%

However it generate syntax error. If I change the character \ backslash to any other letter, e.g. 'abc'. It works. Like this.

%OneVariable + '\' + AnotherVariable%

Is there any workaround? for example in some other language I can use CHR(92) to replace this backslash.

Thank you.

Sorry I have put wrong sequence of the sample code in my post above. It should be like this:

This one generates syntax error:
%OneVariable + '\' + AnotherVariable%

This one works well:
%OneVariable + 'abc' + AnotherVariable%

This is a file path that joins 3 vars to make the full path, is this what you're after ?

%NewVar%%NewVar2%%NewVar3%

Thank you for your reply. I would like to join two variables together to make the full path.

Just when I type here, it seems that I found the solution. I tried using '//' two backslash and it seems work well.

Thank you for your help!

sorry, a typo. It should be '\\' instead of '//'. In summary, if I would like to use backslash during joining two or more text variables, I found I need to use '\\' to avoid syntax error.

This will generate syntax error:
%OneVariable + '\' + AnotherVariable%

This will not generate syntax error:
%OneVariable + '\\' + AnotherVariable%

Well you could always set a var.
var name = %Slash% with a value of \

Therefore
%NewVar%%Slash%%NewVar2%%Slash%%NewVar3%
