RE: st: time elapsed within 'for' loops
I doubt it. -for- itself is a command. The fact
that it runs other commands is not reflected
by what the profiler reports, as is explained
in the help Mark quotes here.
A quite different comment is beware -for-
and the habit of trying to write miniature programs
as a single call to -for-. It is cute when it
works but very inefficient and all too likely to bite you.
