[OS X TeX] Concatinating backslash and id

[Peder Axensten]

Thank you very much!

A variant of the question:
If I want to write the newcommand to a text file, something like:

	\immediate\write\fileid{\newcommand{\#1}{#2}}%

The same problem here, I want to concatenate \ and #1. How can I do  
that?
