backslash in calc

[Rainy Pass]

How/can I use a backslash in a field calculation (test result):

i.e., Field & "" & Field

[Raybaudi]

Use another backslash to escape the second one:

Field & "" & Field

The backslash, like the quote, needs to be escaped with the "escape" char, that is the backslash.
