string concatenation with special characters

[Ali Khawaja]

i am trying to append a backslash between two string variables.

dc + '/' + item

this works fine.  but what i need is backslash.  i could not figure how to insert a backslash. i have tried two backslashes, lot of other trial and error but nothing works.  can anyone please let me know what the issue is, and why simple string contatenation with an escape character does not work?

Thanks

Ali
