Dear Statalist,

I want to systematically use -capture noisily- throughout a do-file with multiple loops (as some fail).

The shortest form for it is -cap n-

Not bad. However, I thought it would be neater to have something even shorter, say -cn-. Unfortunately that's an "unrecognized command" (implemented in a future version of Stata maybe?)

I defined a macro to store "capture noisily" and repeatedly use the macro. See the example code below.

I used a "global" macro so that I could use the dollar sign in front of it -- easy to type and remember.

The trick seems to work, but is it an acceptable practice? any pitfalls?

many thanks.
