Fabio,

Some problems resolve to SET based operations that don't require any loops at all.

The coding standards I prefer to use do not use m. In my opinion it makes the code less readable and less transportable to other codebases like C# and SQL that I use. If a developer takes proper care to not use variable names that conflict with field names there is no issue.

And where I find myself writing a loop that executes enough iterations that using m.i for the loop counter would make a significant performance difference I take a step back and ask the question: "Can this be done with a single set based statement?" to get rid of the loop entirely.
